This review aims to synthesize a published set of evaluative criteria for good qualitative research. The aim is to shed light on existing standards for assessing the rigor of qualitative research encompassing a range of epistemological and ontological standpoints. Using a systematic search strategy, published journal articles that deliberate criteria for rigorous research were identified. Then, references of relevant articles were surveyed to find noteworthy, distinct, and well-defined pointers to good qualitative research. This review presents an investigative assessment of the pivotal features in qualitative research that can permit the readers to pass judgment on its quality and to condemn it as good research when objectively and adequately utilized. Overall, this review underlines the crux of qualitative research and accentuates the necessity to evaluate such research by the very tenets of its being. It also offers some prospects and recommendations to improve the quality of qualitative research. Based on the findings of this review, it is concluded that quality criteria are the aftereffect of socio-institutional procedures and existing paradigmatic conducts. Owing to the paradigmatic diversity of qualitative research, a single and specific set of quality criteria is neither feasible nor anticipated. Since qualitative research is not a cohesive discipline, researchers need to educate and familiarize themselves with applicable norms and decisive factors to evaluate qualitative research from within its theoretical and methodological framework of origin.

Introduction

“… It is important to regularly dialogue about what makes for good qualitative research” (Tracy, 2010 , p. 837)

To decide what represents good qualitative research is highly debatable. There are numerous methods that are contained within qualitative research and that are established on diverse philosophical perspectives. Bryman et al., ( 2008 , p. 262) suggest that “It is widely assumed that whereas quality criteria for quantitative research are well‐known and widely agreed, this is not the case for qualitative research.” Hence, the question “how to evaluate the quality of qualitative research” has been continuously debated. There are many areas of science and technology wherein these debates on the assessment of qualitative research have taken place. Examples include various areas of psychology: general psychology (Madill et al., 2000 ); counseling psychology (Morrow, 2005 ); and clinical psychology (Barker & Pistrang, 2005 ), and other disciplines of social sciences: social policy (Bryman et al., 2008 ); health research (Sparkes, 2001 ); business and management research (Johnson et al., 2006 ); information systems (Klein & Myers, 1999 ); and environmental studies (Reid & Gough, 2000 ). In the literature, these debates are enthused by the impression that the blanket application of criteria for good qualitative research developed around the positivist paradigm is improper. Such debates are based on the wide range of philosophical backgrounds within which qualitative research is conducted (e.g., Sandberg, 2000 ; Schwandt, 1996 ). The existence of methodological diversity led to the formulation of different sets of criteria applicable to qualitative research.

Among qualitative researchers, the dilemma of governing the measures to assess the quality of research is not a new phenomenon, especially when the virtuous triad of objectivity, reliability, and validity (Spencer et al., 2004 ) are not adequate. Occasionally, the criteria of quantitative research are used to evaluate qualitative research (Cohen & Crabtree, 2008 ; Lather, 2004 ). Indeed, Howe ( 2004 ) claims that the prevailing paradigm in educational research is scientifically based experimental research. Hypotheses and conjectures about the preeminence of quantitative research can weaken the worth and usefulness of qualitative research by neglecting the prominence of harmonizing match for purpose on research paradigm, the epistemological stance of the researcher, and the choice of methodology. Researchers have been reprimanded concerning this in “paradigmatic controversies, contradictions, and emerging confluences” (Lincoln & Guba, 2000 ).

In general, qualitative research tends to come from a very different paradigmatic stance and intrinsically demands distinctive and out-of-the-ordinary criteria for evaluating good research and varieties of research contributions that can be made. This review attempts to present a series of evaluative criteria for qualitative researchers, arguing that their choice of criteria needs to be compatible with the unique nature of the research in question (its methodology, aims, and assumptions). This review aims to assist researchers in identifying some of the indispensable features or markers of high-quality qualitative research. In a nutshell, the purpose of this systematic literature review is to analyze the existing knowledge on high-quality qualitative research and to verify the existence of research studies dealing with the critical assessment of qualitative research based on the concept of diverse paradigmatic stances. Contrary to the existing reviews, this review also suggests some critical directions to follow to improve the quality of qualitative research in different epistemological and ontological perspectives. This review is also intended to provide guidelines for the acceleration of future developments and dialogues among qualitative researchers in the context of assessing the qualitative research.

The rest of this review article is structured in the following fashion: Sect.  Methods describes the method followed for performing this review. Section Criteria for Evaluating Qualitative Studies provides a comprehensive description of the criteria for evaluating qualitative studies. This section is followed by a summary of the strategies to improve the quality of qualitative research in Sect.  Improving Quality: Strategies . Section  How to Assess the Quality of the Research Findings? provides details on how to assess the quality of the research findings. After that, some of the quality checklists (as tools to evaluate quality) are discussed in Sect.  Quality Checklists: Tools for Assessing the Quality . At last, the review ends with the concluding remarks presented in Sect.  Conclusions, Future Directions and Outlook . Some prospects in qualitative research for enhancing its quality and usefulness in the social and techno-scientific research community are also presented in Sect.  Conclusions, Future Directions and Outlook .

For this review, a comprehensive literature search was performed from many databases using generic search terms such as Qualitative Research , Criteria , etc . The following databases were chosen for the literature search based on the high number of results: IEEE Explore, ScienceDirect, PubMed, Google Scholar, and Web of Science. The following keywords (and their combinations using Boolean connectives OR/AND) were adopted for the literature search: qualitative research, criteria, quality, assessment, and validity. The synonyms for these keywords were collected and arranged in a logical structure (see Table 1 ). All publications in journals and conference proceedings later than 1950 till 2021 were considered for the search. Other articles extracted from the references of the papers identified in the electronic search were also included. A large number of publications on qualitative research were retrieved during the initial screening. Hence, to include the searches with the main focus on criteria for good qualitative research, an inclusion criterion was utilized in the search string.

From the selected databases, the search retrieved a total of 765 publications. Then, the duplicate records were removed. After that, based on the title and abstract, the remaining 426 publications were screened for their relevance by using the following inclusion and exclusion criteria (see Table 2 ). Publications focusing on evaluation criteria for good qualitative research were included, whereas those works which delivered theoretical concepts on qualitative research were excluded. Based on the screening and eligibility, 45 research articles were identified that offered explicit criteria for evaluating the quality of qualitative research and were found to be relevant to this review.

Criteria for Evaluating Qualitative Studies

Fundamental criteria: general research quality.

Various researchers have put forward criteria for evaluating qualitative research, which have been summarized in Table 3 . Also, the criteria outlined in Table 4 effectively deliver the various approaches to evaluate and assess the quality of qualitative work. The entries in Table 4 are based on Tracy’s “Eight big‐tent criteria for excellent qualitative research” (Tracy, 2010 ). Tracy argues that high-quality qualitative work should formulate criteria focusing on the worthiness, relevance, timeliness, significance, morality, and practicality of the research topic, and the ethical stance of the research itself. Researchers have also suggested a series of questions as guiding principles to assess the quality of a qualitative study (Mays & Pope, 2020 ). Nassaji ( 2020 ) argues that good qualitative research should be robust, well informed, and thoroughly documented.

Qualitative Research: Interpretive Paradigms

All qualitative researchers follow highly abstract principles which bring together beliefs about ontology, epistemology, and methodology. These beliefs govern how the researcher perceives and acts. The net, which encompasses the researcher’s epistemological, ontological, and methodological premises, is referred to as a paradigm, or an interpretive structure, a “Basic set of beliefs that guides action” (Guba, 1990 ). Four major interpretive paradigms structure the qualitative research: positivist and postpositivist, constructivist interpretive, critical (Marxist, emancipatory), and feminist poststructural. The complexity of these four abstract paradigms increases at the level of concrete, specific interpretive communities. Table 5 presents these paradigms and their assumptions, including their criteria for evaluating research, and the typical form that an interpretive or theoretical statement assumes in each paradigm. Moreover, for evaluating qualitative research, quantitative conceptualizations of reliability and validity are proven to be incompatible (Horsburgh, 2003 ). In addition, a series of questions have been put forward in the literature to assist a reviewer (who is proficient in qualitative methods) for meticulous assessment and endorsement of qualitative research (Morse, 2003 ). Hammersley ( 2007 ) also suggests that guiding principles for qualitative research are advantageous, but methodological pluralism should not be simply acknowledged for all qualitative approaches. Seale ( 1999 ) also points out the significance of methodological cognizance in research studies.

Table 5 reflects that criteria for assessing the quality of qualitative research are the aftermath of socio-institutional practices and existing paradigmatic standpoints. Owing to the paradigmatic diversity of qualitative research, a single set of quality criteria is neither possible nor desirable. Hence, the researchers must be reflexive about the criteria they use in the various roles they play within their research community.

Improving Quality: Strategies

Another critical question is “How can the qualitative researchers ensure that the abovementioned quality criteria can be met?” Lincoln and Guba ( 1986 ) delineated several strategies to intensify each criteria of trustworthiness. Other researchers (Merriam & Tisdell, 2016 ; Shenton, 2004 ) also presented such strategies. A brief description of these strategies is shown in Table 6 .

It is worth mentioning that generalizability is also an integral part of qualitative research (Hays & McKibben, 2021 ). In general, the guiding principle pertaining to generalizability speaks about inducing and comprehending knowledge to synthesize interpretive components of an underlying context. Table 7 summarizes the main metasynthesis steps required to ascertain generalizability in qualitative research.

Figure  2 reflects the crucial components of a conceptual framework and their contribution to decisions regarding research design, implementation, and applications of results to future thinking, study, and practice (Johnson et al., 2020 ). The synergy and interrelationship of these components signifies their role to different stances of a qualitative research study.

Essential elements of a conceptual framework

In a nutshell, to assess the rationale of a study, its conceptual framework and research question(s), quality criteria must take account of the following: lucid context for the problem statement in the introduction; well-articulated research problems and questions; precise conceptual framework; distinct research purpose; and clear presentation and investigation of the paradigms. These criteria would expedite the quality of qualitative research.

How to Assess the Quality of the Research Findings?

The inclusion of quotes or similar research data enhances the confirmability in the write-up of the findings. The use of expressions (for instance, “80% of all respondents agreed that” or “only one of the interviewees mentioned that”) may also quantify qualitative findings (Stenfors et al., 2020 ). On the other hand, the persuasive reason for “why this may not help in intensifying the research” has also been provided (Monrouxe & Rees, 2020 ). Further, the Discussion and Conclusion sections of an article also prove robust markers of high-quality qualitative research, as elucidated in Table 8 .

Quality Checklists: Tools for Assessing the Quality

Numerous checklists are available to speed up the assessment of the quality of qualitative research. However, if used uncritically and recklessly concerning the research context, these checklists may be counterproductive. I recommend that such lists and guiding principles may assist in pinpointing the markers of high-quality qualitative research. However, considering enormous variations in the authors’ theoretical and philosophical contexts, I would emphasize that high dependability on such checklists may say little about whether the findings can be applied in your setting. A combination of such checklists might be appropriate for novice researchers. Some of these checklists are listed below:

The most commonly used framework is Consolidated Criteria for Reporting Qualitative Research (COREQ) (Tong et al., 2007 ). This framework is recommended by some journals to be followed by the authors during article submission.

Standards for Reporting Qualitative Research (SRQR) is another checklist that has been created particularly for medical education (O’Brien et al., 2014 ).

Also, Tracy ( 2010 ) and Critical Appraisal Skills Programme (CASP, 2021 ) offer criteria for qualitative research relevant across methods and approaches.

Further, researchers have also outlined different criteria as hallmarks of high-quality qualitative research. For instance, the “Road Trip Checklist” (Epp & Otnes, 2021 ) provides a quick reference to specific questions to address different elements of high-quality qualitative research.

Conclusions, Future Directions, and Outlook

This work presents a broad review of the criteria for good qualitative research. In addition, this article presents an exploratory analysis of the essential elements in qualitative research that can enable the readers of qualitative work to judge it as good research when objectively and adequately utilized. In this review, some of the essential markers that indicate high-quality qualitative research have been highlighted. I scope them narrowly to achieve rigor in qualitative research and note that they do not completely cover the broader considerations necessary for high-quality research. This review points out that a universal and versatile one-size-fits-all guideline for evaluating the quality of qualitative research does not exist. In other words, this review also emphasizes the non-existence of a set of common guidelines among qualitative researchers. In unison, this review reinforces that each qualitative approach should be treated uniquely on account of its own distinctive features for different epistemological and disciplinary positions. Owing to the sensitivity of the worth of qualitative research towards the specific context and the type of paradigmatic stance, researchers should themselves analyze what approaches can be and must be tailored to ensemble the distinct characteristics of the phenomenon under investigation. Although this article does not assert to put forward a magic bullet and to provide a one-stop solution for dealing with dilemmas about how, why, or whether to evaluate the “goodness” of qualitative research, it offers a platform to assist the researchers in improving their qualitative studies. This work provides an assembly of concerns to reflect on, a series of questions to ask, and multiple sets of criteria to look at, when attempting to determine the quality of qualitative research. Overall, this review underlines the crux of qualitative research and accentuates the need to evaluate such research by the very tenets of its being. Bringing together the vital arguments and delineating the requirements that good qualitative research should satisfy, this review strives to equip the researchers as well as reviewers to make well-versed judgment about the worth and significance of the qualitative research under scrutiny. In a nutshell, a comprehensive portrayal of the research process (from the context of research to the research objectives, research questions and design, speculative foundations, and from approaches of collecting data to analyzing the results, to deriving inferences) frequently proliferates the quality of a qualitative research.

Prospects : A Road Ahead for Qualitative Research

Irrefutably, qualitative research is a vivacious and evolving discipline wherein different epistemological and disciplinary positions have their own characteristics and importance. In addition, not surprisingly, owing to the sprouting and varied features of qualitative research, no consensus has been pulled off till date. Researchers have reflected various concerns and proposed several recommendations for editors and reviewers on conducting reviews of critical qualitative research (Levitt et al., 2021 ; McGinley et al., 2021 ). Following are some prospects and a few recommendations put forward towards the maturation of qualitative research and its quality evaluation:

In general, most of the manuscript and grant reviewers are not qualitative experts. Hence, it is more likely that they would prefer to adopt a broad set of criteria. However, researchers and reviewers need to keep in mind that it is inappropriate to utilize the same approaches and conducts among all qualitative research. Therefore, future work needs to focus on educating researchers and reviewers about the criteria to evaluate qualitative research from within the suitable theoretical and methodological context.

There is an urgent need to refurbish and augment critical assessment of some well-known and widely accepted tools (including checklists such as COREQ, SRQR) to interrogate their applicability on different aspects (along with their epistemological ramifications).

Efforts should be made towards creating more space for creativity, experimentation, and a dialogue between the diverse traditions of qualitative research. This would potentially help to avoid the enforcement of one's own set of quality criteria on the work carried out by others.

Moreover, journal reviewers need to be aware of various methodological practices and philosophical debates.

It is pivotal to highlight the expressions and considerations of qualitative researchers and bring them into a more open and transparent dialogue about assessing qualitative research in techno-scientific, academic, sociocultural, and political rooms.

Frequent debates on the use of evaluative criteria are required to solve some potentially resolved issues (including the applicability of a single set of criteria in multi-disciplinary aspects). Such debates would not only benefit the group of qualitative researchers themselves, but primarily assist in augmenting the well-being and vivacity of the entire discipline.

To conclude, I speculate that the criteria, and my perspective, may transfer to other methods, approaches, and contexts. I hope that they spark dialog and debate – about criteria for excellent qualitative research and the underpinnings of the discipline more broadly – and, therefore, help improve the quality of a qualitative study. Further, I anticipate that this review will assist the researchers to contemplate on the quality of their own research, to substantiate research design and help the reviewers to review qualitative research for journals. On a final note, I pinpoint the need to formulate a framework (encompassing the prerequisites of a qualitative study) by the cohesive efforts of qualitative researchers of different disciplines with different theoretic-paradigmatic origins. I believe that tailoring such a framework (of guiding principles) paves the way for qualitative researchers to consolidate the status of qualitative research in the wide-ranging open science debate. Dialogue on this issue across different approaches is crucial for the impending prospects of socio-techno-educational research.

13.1 Formatting a Research Paper

Learning objectives.

• Identify the major components of a research paper written using American Psychological Association (APA) style.
• Apply general APA style and formatting conventions in a research paper.

In this chapter, you will learn how to use APA style , the documentation and formatting style followed by the American Psychological Association, as well as MLA style , from the Modern Language Association. There are a few major formatting styles used in academic texts, including AMA, Chicago, and Turabian:

• AMA (American Medical Association) for medicine, health, and biological sciences
• APA (American Psychological Association) for education, psychology, and the social sciences
• Chicago—a common style used in everyday publications like magazines, newspapers, and books
• MLA (Modern Language Association) for English, literature, arts, and humanities
• Turabian—another common style designed for its universal application across all subjects and disciplines

While all the formatting and citation styles have their own use and applications, in this chapter we focus our attention on the two styles you are most likely to use in your academic studies: APA and MLA.

If you find that the rules of proper source documentation are difficult to keep straight, you are not alone. Writing a good research paper is, in and of itself, a major intellectual challenge. Having to follow detailed citation and formatting guidelines as well may seem like just one more task to add to an already-too-long list of requirements.

Following these guidelines, however, serves several important purposes. First, it signals to your readers that your paper should be taken seriously as a student’s contribution to a given academic or professional field; it is the literary equivalent of wearing a tailored suit to a job interview. Second, it shows that you respect other people’s work enough to give them proper credit for it. Finally, it helps your reader find additional materials if he or she wishes to learn more about your topic.

Furthermore, producing a letter-perfect APA-style paper need not be burdensome. Yes, it requires careful attention to detail. However, you can simplify the process if you keep these broad guidelines in mind:

• Work ahead whenever you can. Chapter 11 “Writing from Research: What Will I Learn?” includes tips for keeping track of your sources early in the research process, which will save time later on.
• Get it right the first time. Apply APA guidelines as you write, so you will not have much to correct during the editing stage. Again, putting in a little extra time early on can save time later.
• Use the resources available to you. In addition to the guidelines provided in this chapter, you may wish to consult the APA website at http://www.apa.org or the Purdue University Online Writing lab at http://owl.english.purdue.edu , which regularly updates its online style guidelines.

General Formatting Guidelines

This chapter provides detailed guidelines for using the citation and formatting conventions developed by the American Psychological Association, or APA. Writers in disciplines as diverse as astrophysics, biology, psychology, and education follow APA style. The major components of a paper written in APA style are listed in the following box.

These are the major components of an APA-style paper:

• Headings and, if necessary, subheadings to organize the content
• In-text citations of research sources
• References page

All these components must be saved in one document, not as separate documents.

The title page of your paper includes the following information:

• Title of the paper
• Author’s name
• Name of the institution with which the author is affiliated
• Header at the top of the page with the paper title (in capital letters) and the page number (If the title is lengthy, you may use a shortened form of it in the header.)

List the first three elements in the order given in the previous list, centered about one third of the way down from the top of the page. Use the headers and footers tool of your word-processing program to add the header, with the title text at the left and the page number in the upper-right corner. Your title page should look like the following example.

The next page of your paper provides an abstract , or brief summary of your findings. An abstract does not need to be provided in every paper, but an abstract should be used in papers that include a hypothesis. A good abstract is concise—about one hundred fifty to two hundred fifty words—and is written in an objective, impersonal style. Your writing voice will not be as apparent here as in the body of your paper. When writing the abstract, take a just-the-facts approach, and summarize your research question and your findings in a few sentences.

In Chapter 12 “Writing a Research Paper” , you read a paper written by a student named Jorge, who researched the effectiveness of low-carbohydrate diets. Read Jorge’s abstract. Note how it sums up the major ideas in his paper without going into excessive detail.

Write an abstract summarizing your paper. Briefly introduce the topic, state your findings, and sum up what conclusions you can draw from your research. Use the word count feature of your word-processing program to make sure your abstract does not exceed one hundred fifty words.

Depending on your field of study, you may sometimes write research papers that present extensive primary research, such as your own experiment or survey. In your abstract, summarize your research question and your findings, and briefly indicate how your study relates to prior research in the field.

Margins, Pagination, and Headings

APA style requirements also address specific formatting concerns, such as margins, pagination, and heading styles, within the body of the paper. Review the following APA guidelines.

Use these general guidelines to format the paper:

• Set the top, bottom, and side margins of your paper at 1 inch.
• Use double-spaced text throughout your paper.
• Use a standard font, such as Times New Roman or Arial, in a legible size (10- to 12-point).
• Use continuous pagination throughout the paper, including the title page and the references section. Page numbers appear flush right within your header.
• Section headings and subsection headings within the body of your paper use different types of formatting depending on the level of information you are presenting. Additional details from Jorge’s paper are provided.

Begin formatting the final draft of your paper according to APA guidelines. You may work with an existing document or set up a new document if you choose. Include the following:

• Your title page
• The abstract you created in Note 13.8 “Exercise 1”
• Correct headers and page numbers for your title page and abstract

APA style uses section headings to organize information, making it easy for the reader to follow the writer’s train of thought and to know immediately what major topics are covered. Depending on the length and complexity of the paper, its major sections may also be divided into subsections, sub-subsections, and so on. These smaller sections, in turn, use different heading styles to indicate different levels of information. In essence, you are using headings to create a hierarchy of information.

The following heading styles used in APA formatting are listed in order of greatest to least importance:

• Section headings use centered, boldface type. Headings use title case, with important words in the heading capitalized.
• Subsection headings use left-aligned, boldface type. Headings use title case.
• The third level uses left-aligned, indented, boldface type. Headings use a capital letter only for the first word, and they end in a period.
• The fourth level follows the same style used for the previous level, but the headings are boldfaced and italicized.
• The fifth level follows the same style used for the previous level, but the headings are italicized and not boldfaced.

Visually, the hierarchy of information is organized as indicated in Table 13.1 “Section Headings” .

Table 13.1 Section Headings

A college research paper may not use all the heading levels shown in Table 13.1 “Section Headings” , but you are likely to encounter them in academic journal articles that use APA style. For a brief paper, you may find that level 1 headings suffice. Longer or more complex papers may need level 2 headings or other lower-level headings to organize information clearly. Use your outline to craft your major section headings and determine whether any subtopics are substantial enough to require additional levels of headings.

Working with the document you developed in Note 13.11 “Exercise 2” , begin setting up the heading structure of the final draft of your research paper according to APA guidelines. Include your title and at least two to three major section headings, and follow the formatting guidelines provided above. If your major sections should be broken into subsections, add those headings as well. Use your outline to help you.

Because Jorge used only level 1 headings, his Exercise 3 would look like the following:

Citation Guidelines

In-text citations.

Throughout the body of your paper, include a citation whenever you quote or paraphrase material from your research sources. As you learned in Chapter 11 “Writing from Research: What Will I Learn?” , the purpose of citations is twofold: to give credit to others for their ideas and to allow your reader to follow up and learn more about the topic if desired. Your in-text citations provide basic information about your source; each source you cite will have a longer entry in the references section that provides more detailed information.

In-text citations must provide the name of the author or authors and the year the source was published. (When a given source does not list an individual author, you may provide the source title or the name of the organization that published the material instead.) When directly quoting a source, it is also required that you include the page number where the quote appears in your citation.

This information may be included within the sentence or in a parenthetical reference at the end of the sentence, as in these examples.

Epstein (2010) points out that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (p. 137).

Here, the writer names the source author when introducing the quote and provides the publication date in parentheses after the author’s name. The page number appears in parentheses after the closing quotation marks and before the period that ends the sentence.

Addiction researchers caution that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (Epstein, 2010, p. 137).

Here, the writer provides a parenthetical citation at the end of the sentence that includes the author’s name, the year of publication, and the page number separated by commas. Again, the parenthetical citation is placed after the closing quotation marks and before the period at the end of the sentence.

As noted in the book Junk Food, Junk Science (Epstein, 2010, p. 137), “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive.”

Here, the writer chose to mention the source title in the sentence (an optional piece of information to include) and followed the title with a parenthetical citation. Note that the parenthetical citation is placed before the comma that signals the end of the introductory phrase.

David Epstein’s book Junk Food, Junk Science (2010) pointed out that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (p. 137).

Another variation is to introduce the author and the source title in your sentence and include the publication date and page number in parentheses within the sentence or at the end of the sentence. As long as you have included the essential information, you can choose the option that works best for that particular sentence and source.

Citing a book with a single author is usually a straightforward task. Of course, your research may require that you cite many other types of sources, such as books or articles with more than one author or sources with no individual author listed. You may also need to cite sources available in both print and online and nonprint sources, such as websites and personal interviews. Chapter 13 “APA and MLA Documentation and Formatting” , Section 13.2 “Citing and Referencing Techniques” and Section 13.3 “Creating a References Section” provide extensive guidelines for citing a variety of source types.

Writing at Work

APA is just one of several different styles with its own guidelines for documentation, formatting, and language usage. Depending on your field of interest, you may be exposed to additional styles, such as the following:

• MLA style. Determined by the Modern Languages Association and used for papers in literature, languages, and other disciplines in the humanities.
• Chicago style. Outlined in the Chicago Manual of Style and sometimes used for papers in the humanities and the sciences; many professional organizations use this style for publications as well.
• Associated Press (AP) style. Used by professional journalists.

References List

The brief citations included in the body of your paper correspond to the more detailed citations provided at the end of the paper in the references section. In-text citations provide basic information—the author’s name, the publication date, and the page number if necessary—while the references section provides more extensive bibliographical information. Again, this information allows your reader to follow up on the sources you cited and do additional reading about the topic if desired.

The specific format of entries in the list of references varies slightly for different source types, but the entries generally include the following information:

• The name(s) of the author(s) or institution that wrote the source
• The year of publication and, where applicable, the exact date of publication
• The full title of the source
• For books, the city of publication
• For articles or essays, the name of the periodical or book in which the article or essay appears
• For magazine and journal articles, the volume number, issue number, and pages where the article appears
• For sources on the web, the URL where the source is located

The references page is double spaced and lists entries in alphabetical order by the author’s last name. If an entry continues for more than one line, the second line and each subsequent line are indented five spaces. Review the following example. ( Chapter 13 “APA and MLA Documentation and Formatting” , Section 13.3 “Creating a References Section” provides extensive guidelines for formatting reference entries for different types of sources.)

In APA style, book and article titles are formatted in sentence case, not title case. Sentence case means that only the first word is capitalized, along with any proper nouns.

Key Takeaways

• Following proper citation and formatting guidelines helps writers ensure that their work will be taken seriously, give proper credit to other authors for their work, and provide valuable information to readers.
• Working ahead and taking care to cite sources correctly the first time are ways writers can save time during the editing stage of writing a research paper.
• APA papers usually include an abstract that concisely summarizes the paper.
• APA papers use a specific headings structure to provide a clear hierarchy of information.
• In APA papers, in-text citations usually include the name(s) of the author(s) and the year of publication.
• In-text citations correspond to entries in the references section, which provide detailed bibliographical information about a source.

What makes a high quality clinical research paper?

The quality of a research paper depends primarily on the quality of the research study it reports. However, there is also much that authors can do to maximise the clarity and usefulness of their papers. Journals' instructions for authors often focus on the format, style, and length of articles but do not always emphasise the need to clearly explain the work's science and ethics: so this review reminds researchers that transparency is important too. The research question should be stated clearly, along with an explanation of where it came from and why it is important. The study methods must be reported fully and, where appropriate, in line with an evidence based reporting guideline such as the CONSORT statement for randomised controlled trials. If the study was a trial the paper should state where and when the study was registered and state its registration identifier. Finally, any relevant conflicts of interest should be declared.

What Should Be the Characteristics of a Good Research Paper?

by team@blp

In miscellaneous.

When people want to get answers to various issues, they search for information on the problems. From their findings, they expand them, aiming to agree or refute them. Research papers are common assignments in colleges. 

They follow specific research and writing guidelines to answer particular questions or assigned topics. They look into the critical topic of credible research sources and argue their findings in an orderly manner. To be termed as good, the research paper must bear the following characteristics.

In this Article

Gives credit to previous research work on the topic

• It’s hooked on a relevant research question.

It must be based on appropriate, systematic research methods

• The information must be accurate and controlled.
• It must be verifiable and rigorous.

Be careful with the topic you choose

Decide the sources you want to use, create your thesis statement , plan your points, write your paper, characteristics of a good research paper.

Writing a research paper aims to discover new knowledge, but the knowledge must have a base. Its base is the research done previously by other scholars. The student must acknowledge the previous research and avoid duplicating it in their writing process.

A college student must engage in deep research work to create a credible research paper. This makes the process lengthy and complex when choosing your topic, selecting sources, and developing its design. In addition, it requires a great deal of knowledge to piece everything together. Fortunately, Studyclerk will give you professional help anytime you need it. If you do not have enough knowledge and time to write a paper on your own, you can ask for  research paper help  by StudyClerk, where experienced paper writers will write your paper in no time. You can trust their expert writers to handle your assignment well and get a well-written paper in a short time.

It’s hooked on a relevant research question .

All the time a student spends researching multiple sources is to answer a specific research question. The question must be relevant to the current needs. This question guides them into the information they use or the line of argument they take.

The methodology of research a student chooses will determine the value of the information they get or give. The methods must be valid and credible to provide reliable outcomes. Whether the student chooses a qualitative, quantitative, or mixed approach, they must all be valuable and relevant. 

The information must be accurate and controlled .

A good research paper cannot be generalized information but specific, scientific information. That is why they must include references and record tests or information accurately. Moreover, they must keep the information controlled by staying within the topic from the first step of research to the last. 

It must be verifiable and rigorous .

The student must use information or write arguments that can be verified. If it’s a test, it must be replicable by another researcher. The sources must be verifiable and accurate. Without rigorous deep  research strategies , the paper cannot be good. They must put a lot of labor into both the writing and research processes to ensure the information is credible, clear, concise, original, and precise. 

How to write a good research paper

To write a good research paper, you must first understand what kind of question you have been assigned. Then, you will choose the best topic that you will love to write about. The following points will help you write a good research paper.

You must select a topic you love. Go for a topic that will be easier to research, which will give you a broader area of study. 

Your instructor doesn’t restrict you on the sources you must use. Broaden your mind so that you don’t limit yourself to specific sources of information. Sometimes you will get helpful information from sources you slightest thought as good.

Write your central statement to base your position on the research. Make it coherent contentious, and let it be a summary of your arguments.

Create an outline that will guide you when arguing your points

• Start  with the most vital points and smooth the flow.
• Pay attention to  paragraph structure  and let your arguments be clear.
• Finish with a compelling conclusion, and don’t forget to cite your sources.

A research paper requires extensive research methods to get solid points for supporting your stand. First, the sources you use must be verifiable by any other researcher. You must ensure your research work is original for your paper to be credible. Third, each point should be coherent with each paragraph. Finally, your research findings must be tagged on the research question and provide answers that apply to the current society.

The title summarizes the main idea or ideas of your study. A good title contains the fewest possible words needed to adequately describe the content and/or purpose of your research paper.

Importance of Choosing a Good Title

The title is the part of a paper that is read the most, and it is usually read first . It is, therefore, the most important element that defines the research study. With this in mind, avoid the following when creating a title:

• If the title is too long, this usually indicates there are too many unnecessary words. Avoid language, such as, "A Study to Investigate the...," or "An Examination of the...." These phrases are obvious and generally superfluous unless they are necessary to covey the scope, intent, or type of a study.
• On the other hand, a title which is too short often uses words which are too broad and, thus, does not tell the reader what is being studied. For example, a paper with the title, "African Politics" is so non-specific the title could be the title of a book and so ambiguous that it could refer to anything associated with politics in Africa. A good title should provide information about the focus and/or scope of your research study.
• In academic writing, catchy phrases or non-specific language may be used, but only if it's within the context of the study [e.g., "Fair and Impartial Jury--Catch as Catch Can"]. However, in most cases, you should avoid including words or phrases that do not help the reader understand the purpose of your paper.
• Academic writing is a serious and deliberate endeavor. Avoid using humorous or clever journalistic styles of phrasing when creating the title to your paper. Journalistic headlines often use emotional adjectives [e.g., incredible, amazing, effortless] to highlight a problem experienced by the reader or use "trigger words" or interrogative words like how, what, when, or why to persuade people to read the article or click on a link. These approaches are viewed as counter-productive in academic writing. A reader does not need clever or humorous titles to catch their attention because the act of reading research is assumed to be deliberate based on a desire to learn and improve understanding of the problem. In addition, a humorous title can merely detract from the seriousness and authority of your research. 
• Unlike everywhere else in a college-level social sciences research paper [except when using direct quotes in the text], titles do not have to adhere to rigid grammatical or stylistic standards. For example, it could be appropriate to begin a title with a coordinating conjunction [i.e., and, but, or, nor, for, so, yet] if it makes sense to do so and does not detract from the purpose of the study [e.g., "Yet Another Look at Mutual Fund Tournaments"] or beginning the title with an inflected form of a verb such as those ending in -ing [e.g., "Assessing the Political Landscape: Structure, Cognition, and Power in Organizations"].

Jon F. Nussbaum, editor. (New York: Oxford University Press, 2018): https://oxfordre.com/communication.

Structure and Writing Style

The following parameters can be used to help you formulate a suitable research paper title:

• The purpose of the research
• The scope of the research
• The narrative tone of the paper [typically defined by the type of the research]
• The methods used to study the problem

The initial aim of a title is to capture the reader’s attention and to highlight the research problem under investigation.

Create a Working Title Typically, the final title you submit to your professor is created after the research is complete so that the title accurately captures what has been done . The working title should be developed early in the research process because it can help anchor the focus of the study in much the same way the research problem does. Referring back to the working title can help you reorient yourself back to the main purpose of the study if you find yourself drifting off on a tangent while writing. The Final Title Effective titles in research papers have several characteristics that reflect general principles of academic writing.

• Indicate accurately the subject and scope of the study,
• Rarely use abbreviations or acronyms unless they are commonly known,
• Use words that create a positive impression and stimulate reader interest,
• Use current nomenclature from the field of study,
• Identify key variables, both dependent and independent,
• Reveal how the paper will be organized,
• Suggest a relationship between variables which supports the major hypothesis,
• Is limited to 5 to 15 substantive words,
• Does not include redundant phrasing, such as, "A Study of," "An Analysis of" or similar constructions,
• Takes the form of a question or declarative statement,
• If you use a quote as part of the title, the source of the quote is cited [usually using an asterisk and footnote],
• Use correct grammar and capitalization with all first words and last words capitalized, including the first word of a subtitle. All nouns, pronouns, verbs, adjectives, and adverbs that appear between the first and last words of the title are also capitalized, and
• Rarely uses an exclamation mark at the end of the title.

The Subtitle Subtitles are frequently used in social sciences research papers because it helps the reader understand the scope of the study in relation to how it was designed to address the research problem. Think about what type of subtitle listed below reflects the overall approach to your study and whether you believe a subtitle is needed to emphasize the investigative parameters of your research.

1.  Explains or provides additional context , e.g., "Linguistic Ethnography and the Study of Welfare Institutions as a Flow of Social Practices: The Case of Residential Child Care Institutions as Paradoxical Institutions." [Palomares, Manuel and David Poveda.  Text & Talk: An Interdisciplinary Journal of Language, Discourse and Communication Studies 30 (January 2010): 193-212]

2.  Adds substance to a literary, provocative, or imaginative title or quote , e.g., "Listen to What I Say, Not How I Vote": Congressional Support for the President in Washington and at Home." [Grose, Christian R. and Keesha M. Middlemass. Social Science Quarterly 91 (March 2010): 143-167]

3.  Qualifies the geographic scope of the research , e.g., "The Geopolitics of the Eastern Border of the European Union: The Case of Romania-Moldova-Ukraine." [Marcu, Silvia. Geopolitics 14 (August 2009): 409-432]

4.  Qualifies the temporal scope of the research , e.g., "A Comparison of the Progressive Era and the Depression Years: Societal Influences on Predictions of the Future of the Library, 1895-1940." [Grossman, Hal B. Libraries & the Cultural Record 46 (2011): 102-128]

5.  Focuses on investigating the ideas, theories, or work of a particular individual , e.g., "A Deliberative Conception of Politics: How Francesco Saverio Merlino Related Anarchy and Democracy." [La Torre, Massimo. Sociologia del Diritto 28 (January 2001): 75 - 98]

6.  Identifies the methodology used , e.g. "Student Activism of the 1960s Revisited: A Multivariate Analysis Research Note." [Aron, William S. Social Forces 52 (March 1974): 408-414]

7.  Defines the overarching technique for analyzing the research problem , e.g., "Explaining Territorial Change in Federal Democracies: A Comparative Historical Institutionalist Approach." [ Tillin, Louise. Political Studies 63 (August 2015): 626-641.

With these examples in mind, think about what type of subtitle reflects the overall approach to your study. This will help the reader understand the scope of the study in relation to how it was designed to address the research problem.

Writing the title and abstract for a research paper: Being concise, precise, and meticulous is the key

Milind s. tullu.

Department of Pediatrics, Seth G.S. Medical College and KEM Hospital, Parel, Mumbai, Maharashtra, India

This article deals with formulating a suitable title and an appropriate abstract for an original research paper. The “title” and the “abstract” are the “initial impressions” of a research article, and hence they need to be drafted correctly, accurately, carefully, and meticulously. Often both of these are drafted after the full manuscript is ready. Most readers read only the title and the abstract of a research paper and very few will go on to read the full paper. The title and the abstract are the most important parts of a research paper and should be pleasant to read. The “title” should be descriptive, direct, accurate, appropriate, interesting, concise, precise, unique, and should not be misleading. The “abstract” needs to be simple, specific, clear, unbiased, honest, concise, precise, stand-alone, complete, scholarly, (preferably) structured, and should not be misrepresentative. The abstract should be consistent with the main text of the paper, especially after a revision is made to the paper and should include the key message prominently. It is very important to include the most important words and terms (the “keywords”) in the title and the abstract for appropriate indexing purpose and for retrieval from the search engines and scientific databases. Such keywords should be listed after the abstract. One must adhere to the instructions laid down by the target journal with regard to the style and number of words permitted for the title and the abstract.

Introduction

This article deals with drafting a suitable “title” and an appropriate “abstract” for an original research paper. Because the “title” and the “abstract” are the “initial impressions” or the “face” of a research article, they need to be drafted correctly, accurately, carefully, meticulously, and consume time and energy.[ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 ] Often, these are drafted after the complete manuscript draft is ready.[ 2 , 3 , 4 , 5 , 9 , 10 , 11 ] Most readers will read only the title and the abstract of a published research paper, and very few “interested ones” (especially, if the paper is of use to them) will go on to read the full paper.[ 1 , 2 ] One must remember to adhere to the instructions laid down by the “target journal” (the journal for which the author is writing) regarding the style and number of words permitted for the title and the abstract.[ 2 , 4 , 5 , 7 , 8 , 9 , 12 ] Both the title and the abstract are the most important parts of a research paper – for editors (to decide whether to process the paper for further review), for reviewers (to get an initial impression of the paper), and for the readers (as these may be the only parts of the paper available freely and hence, read widely).[ 4 , 8 , 12 ] It may be worth for the novice author to browse through titles and abstracts of several prominent journals (and their target journal as well) to learn more about the wording and styles of the titles and abstracts, as well as the aims and scope of the particular journal.[ 5 , 7 , 9 , 13 ]

The details of the title are discussed under the subheadings of importance, types, drafting, and checklist.

Importance of the title

When a reader browses through the table of contents of a journal issue (hard copy or on website), the title is the “ first detail” or “face” of the paper that is read.[ 2 , 3 , 4 , 5 , 6 , 13 ] Hence, it needs to be simple, direct, accurate, appropriate, specific, functional, interesting, attractive/appealing, concise/brief, precise/focused, unambiguous, memorable, captivating, informative (enough to encourage the reader to read further), unique, catchy, and it should not be misleading.[ 1 , 2 , 3 , 4 , 5 , 6 , 9 , 12 ] It should have “just enough details” to arouse the interest and curiosity of the reader so that the reader then goes ahead with studying the abstract and then (if still interested) the full paper.[ 1 , 2 , 4 , 13 ] Journal websites, electronic databases, and search engines use the words in the title and abstract (the “keywords”) to retrieve a particular paper during a search; hence, the importance of these words in accessing the paper by the readers has been emphasized.[ 3 , 4 , 5 , 6 , 12 , 14 ] Such important words (or keywords) should be arranged in appropriate order of importance as per the context of the paper and should be placed at the beginning of the title (rather than the later part of the title, as some search engines like Google may just display only the first six to seven words of the title).[ 3 , 5 , 12 ] Whimsical, amusing, or clever titles, though initially appealing, may be missed or misread by the busy reader and very short titles may miss the essential scientific words (the “keywords”) used by the indexing agencies to catch and categorize the paper.[ 1 , 3 , 4 , 9 ] Also, amusing or hilarious titles may be taken less seriously by the readers and may be cited less often.[ 4 , 15 ] An excessively long or complicated title may put off the readers.[ 3 , 9 ] It may be a good idea to draft the title after the main body of the text and the abstract are drafted.[ 2 , 3 , 4 , 5 ]

Types of titles

Titles can be descriptive, declarative, or interrogative. They can also be classified as nominal, compound, or full-sentence titles.

Descriptive or neutral title

This has the essential elements of the research theme, that is, the patients/subjects, design, interventions, comparisons/control, and outcome, but does not reveal the main result or the conclusion.[ 3 , 4 , 12 , 16 ] Such a title allows the reader to interpret the findings of the research paper in an impartial manner and with an open mind.[ 3 ] These titles also give complete information about the contents of the article, have several keywords (thus increasing the visibility of the article in search engines), and have increased chances of being read and (then) being cited as well.[ 4 ] Hence, such descriptive titles giving a glimpse of the paper are generally preferred.[ 4 , 16 ]

Declarative title

This title states the main finding of the study in the title itself; it reduces the curiosity of the reader, may point toward a bias on the part of the author, and hence is best avoided.[ 3 , 4 , 12 , 16 ]

Interrogative title

This is the one which has a query or the research question in the title.[ 3 , 4 , 16 ] Though a query in the title has the ability to sensationalize the topic, and has more downloads (but less citations), it can be distracting to the reader and is again best avoided for a research article (but can, at times, be used for a review article).[ 3 , 6 , 16 , 17 ]

From a sentence construct point of view, titles may be nominal (capturing only the main theme of the study), compound (with subtitles to provide additional relevant information such as context, design, location/country, temporal aspect, sample size, importance, and a provocative or a literary; for example, see the title of this review), or full-sentence titles (which are longer and indicate an added degree of certainty of the results).[ 4 , 6 , 9 , 16 ] Any of these constructs may be used depending on the type of article, the key message, and the author's preference or judgement.[ 4 ]

Drafting a suitable title

A stepwise process can be followed to draft the appropriate title. The author should describe the paper in about three sentences, avoiding the results and ensuring that these sentences contain important scientific words/keywords that describe the main contents and subject of the paper.[ 1 , 4 , 6 , 12 ] Then the author should join the sentences to form a single sentence, shorten the length (by removing redundant words or adjectives or phrases), and finally edit the title (thus drafted) to make it more accurate, concise (about 10–15 words), and precise.[ 1 , 3 , 4 , 5 , 9 ] Some journals require that the study design be included in the title, and this may be placed (using a colon) after the primary title.[ 2 , 3 , 4 , 14 ] The title should try to incorporate the Patients, Interventions, Comparisons and Outcome (PICO).[ 3 ] The place of the study may be included in the title (if absolutely necessary), that is, if the patient characteristics (such as study population, socioeconomic conditions, or cultural practices) are expected to vary as per the country (or the place of the study) and have a bearing on the possible outcomes.[ 3 , 6 ] Lengthy titles can be boring and appear unfocused, whereas very short titles may not be representative of the contents of the article; hence, optimum length is required to ensure that the title explains the main theme and content of the manuscript.[ 4 , 5 , 9 ] Abbreviations (except the standard or commonly interpreted ones such as HIV, AIDS, DNA, RNA, CDC, FDA, ECG, and EEG) or acronyms should be avoided in the title, as a reader not familiar with them may skip such an article and nonstandard abbreviations may create problems in indexing the article.[ 3 , 4 , 5 , 6 , 9 , 12 ] Also, too much of technical jargon or chemical formulas in the title may confuse the readers and the article may be skipped by them.[ 4 , 9 ] Numerical values of various parameters (stating study period or sample size) should also be avoided in the titles (unless deemed extremely essential).[ 4 ] It may be worthwhile to take an opinion from a impartial colleague before finalizing the title.[ 4 , 5 , 6 ] Thus, multiple factors (which are, at times, a bit conflicting or contrasting) need to be considered while formulating a title, and hence this should not be done in a hurry.[ 4 , 6 ] Many journals ask the authors to draft a “short title” or “running head” or “running title” for printing in the header or footer of the printed paper.[ 3 , 12 ] This is an abridged version of the main title of up to 40–50 characters, may have standard abbreviations, and helps the reader to navigate through the paper.[ 3 , 12 , 14 ]

Checklist for a good title

Table 1 gives a checklist/useful tips for drafting a good title for a research paper.[ 1 , 2 , 3 , 4 , 5 , 6 , 12 ] Table 2 presents some of the titles used by the author of this article in his earlier research papers, and the appropriateness of the titles has been commented upon. As an individual exercise, the reader may try to improvise upon the titles (further) after reading the corresponding abstract and full paper.

The Abstract

The details of the abstract are discussed under the subheadings of importance, types, drafting, and checklist.

Importance of the abstract

The abstract is a summary or synopsis of the full research paper and also needs to have similar characteristics like the title. It needs to be simple, direct, specific, functional, clear, unbiased, honest, concise, precise, self-sufficient, complete, comprehensive, scholarly, balanced, and should not be misleading.[ 1 , 2 , 3 , 7 , 8 , 9 , 10 , 11 , 13 , 17 ] Writing an abstract is to extract and summarize (AB – absolutely, STR – straightforward, ACT – actual data presentation and interpretation).[ 17 ] The title and abstracts are the only sections of the research paper that are often freely available to the readers on the journal websites, search engines, and in many abstracting agencies/databases, whereas the full paper may attract a payment per view or a fee for downloading the pdf copy.[ 1 , 2 , 3 , 7 , 8 , 10 , 11 , 13 , 14 ] The abstract is an independent and stand-alone (that is, well understood without reading the full paper) section of the manuscript and is used by the editor to decide the fate of the article and to choose appropriate reviewers.[ 2 , 7 , 10 , 12 , 13 ] Even the reviewers are initially supplied only with the title and the abstract before they agree to review the full manuscript.[ 7 , 13 ] This is the second most commonly read part of the manuscript, and therefore it should reflect the contents of the main text of the paper accurately and thus act as a “real trailer” of the full article.[ 2 , 7 , 11 ] The readers will go through the full paper only if they find the abstract interesting and relevant to their practice; else they may skip the paper if the abstract is unimpressive.[ 7 , 8 , 9 , 10 , 13 ] The abstract needs to highlight the selling point of the manuscript and succeed in luring the reader to read the complete paper.[ 3 , 7 ] The title and the abstract should be constructed using keywords (key terms/important words) from all the sections of the main text.[ 12 ] Abstracts are also used for submitting research papers to a conference for consideration for presentation (as oral paper or poster).[ 9 , 13 , 17 ] Grammatical and typographic errors reflect poorly on the quality of the abstract, may indicate carelessness/casual attitude on part of the author, and hence should be avoided at all times.[ 9 ]

Types of abstracts

The abstracts can be structured or unstructured. They can also be classified as descriptive or informative abstracts.

Structured and unstructured abstracts

Structured abstracts are followed by most journals, are more informative, and include specific subheadings/subsections under which the abstract needs to be composed.[ 1 , 7 , 8 , 9 , 10 , 11 , 13 , 17 , 18 ] These subheadings usually include context/background, objectives, design, setting, participants, interventions, main outcome measures, results, and conclusions.[ 1 ] Some journals stick to the standard IMRAD format for the structure of the abstracts, and the subheadings would include Introduction/Background, Methods, Results, And (instead of Discussion) the Conclusion/s.[ 1 , 2 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 17 , 18 ] Structured abstracts are more elaborate, informative, easy to read, recall, and peer-review, and hence are preferred; however, they consume more space and can have same limitations as an unstructured abstract.[ 7 , 9 , 18 ] The structured abstracts are (possibly) better understood by the reviewers and readers. Anyway, the choice of the type of the abstract and the subheadings of a structured abstract depend on the particular journal style and is not left to the author's wish.[ 7 , 10 , 12 ] Separate subheadings may be necessary for reporting meta-analysis, educational research, quality improvement work, review, or case study.[ 1 ] Clinical trial abstracts need to include the essential items mentioned in the CONSORT (Consolidated Standards Of Reporting Trials) guidelines.[ 7 , 9 , 14 , 19 ] Similar guidelines exist for various other types of studies, including observational studies and for studies of diagnostic accuracy.[ 20 , 21 ] A useful resource for the above guidelines is available at www.equator-network.org (Enhancing the QUAlity and Transparency Of health Research). Unstructured (or non-structured) abstracts are free-flowing, do not have predefined subheadings, and are commonly used for papers that (usually) do not describe original research.[ 1 , 7 , 9 , 10 ]

The four-point structured abstract: This has the following elements which need to be properly balanced with regard to the content/matter under each subheading:[ 9 ]

Background and/or Objectives: This states why the work was undertaken and is usually written in just a couple of sentences.[ 3 , 7 , 8 , 9 , 10 , 12 , 13 ] The hypothesis/study question and the major objectives are also stated under this subheading.[ 3 , 7 , 8 , 9 , 10 , 12 , 13 ]

Methods: This subsection is the longest, states what was done, and gives essential details of the study design, setting, participants, blinding, sample size, sampling method, intervention/s, duration and follow-up, research instruments, main outcome measures, parameters evaluated, and how the outcomes were assessed or analyzed.[ 3 , 7 , 8 , 9 , 10 , 12 , 13 , 14 , 17 ]

Results/Observations/Findings: This subheading states what was found, is longer, is difficult to draft, and needs to mention important details including the number of study participants, results of analysis (of primary and secondary objectives), and include actual data (numbers, mean, median, standard deviation, “P” values, 95% confidence intervals, effect sizes, relative risks, odds ratio, etc.).[ 3 , 7 , 8 , 9 , 10 , 12 , 13 , 14 , 17 ]

Conclusions: The take-home message (the “so what” of the paper) and other significant/important findings should be stated here, considering the interpretation of the research question/hypothesis and results put together (without overinterpreting the findings) and may also include the author's views on the implications of the study.[ 3 , 7 , 8 , 9 , 10 , 12 , 13 , 14 , 17 ]

The eight-point structured abstract: This has the following eight subheadings – Objectives, Study Design, Study Setting, Participants/Patients, Methods/Intervention, Outcome Measures, Results, and Conclusions.[ 3 , 9 , 18 ] The instructions to authors given by the particular journal state whether they use the four- or eight-point abstract or variants thereof.[ 3 , 14 ]

Descriptive and Informative abstracts

Descriptive abstracts are short (75–150 words), only portray what the paper contains without providing any more details; the reader has to read the full paper to know about its contents and are rarely used for original research papers.[ 7 , 10 ] These are used for case reports, reviews, opinions, and so on.[ 7 , 10 ] Informative abstracts (which may be structured or unstructured as described above) give a complete detailed summary of the article contents and truly reflect the actual research done.[ 7 , 10 ]

Drafting a suitable abstract

It is important to religiously stick to the instructions to authors (format, word limit, font size/style, and subheadings) provided by the journal for which the abstract and the paper are being written.[ 7 , 8 , 9 , 10 , 13 ] Most journals allow 200–300 words for formulating the abstract and it is wise to restrict oneself to this word limit.[ 1 , 2 , 3 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 22 ] Though some authors prefer to draft the abstract initially, followed by the main text of the paper, it is recommended to draft the abstract in the end to maintain accuracy and conformity with the main text of the paper (thus maintaining an easy linkage/alignment with title, on one hand, and the introduction section of the main text, on the other hand).[ 2 , 7 , 9 , 10 , 11 ] The authors should check the subheadings (of the structured abstract) permitted by the target journal, use phrases rather than sentences to draft the content of the abstract, and avoid passive voice.[ 1 , 7 , 9 , 12 ] Next, the authors need to get rid of redundant words and edit the abstract (extensively) to the correct word count permitted (every word in the abstract “counts”!).[ 7 , 8 , 9 , 10 , 13 ] It is important to ensure that the key message, focus, and novelty of the paper are not compromised; the rationale of the study and the basis of the conclusions are clear; and that the abstract is consistent with the main text of the paper.[ 1 , 2 , 3 , 7 , 9 , 11 , 12 , 13 , 14 , 17 , 22 ] This is especially important while submitting a revision of the paper (modified after addressing the reviewer's comments), as the changes made in the main (revised) text of the paper need to be reflected in the (revised) abstract as well.[ 2 , 10 , 12 , 14 , 22 ] Abbreviations should be avoided in an abstract, unless they are conventionally accepted or standard; references, tables, or figures should not be cited in the abstract.[ 7 , 9 , 10 , 11 , 13 ] It may be worthwhile not to rush with the abstract and to get an opinion by an impartial colleague on the content of the abstract; and if possible, the full paper (an “informal” peer-review).[ 1 , 7 , 8 , 9 , 11 , 17 ] Appropriate “Keywords” (three to ten words or phrases) should follow the abstract and should be preferably chosen from the Medical Subject Headings (MeSH) list of the U.S. National Library of Medicine ( https://meshb.nlm.nih.gov/search ) and are used for indexing purposes.[ 2 , 3 , 11 , 12 ] These keywords need to be different from the words in the main title (the title words are automatically used for indexing the article) and can be variants of the terms/phrases used in the title, or words from the abstract and the main text.[ 3 , 12 ] The ICMJE (International Committee of Medical Journal Editors; http://www.icmje.org/ ) also recommends publishing the clinical trial registration number at the end of the abstract.[ 7 , 14 ]

9 Steps To Publish A Research Paper

Researchers and scholars undertake academic studies to advance knowledge in their respective fields of study. To this end, they also focus on getting their work published in high-impact and widely read journals. This helps them to highlight and disseminate their work, be known in their respective fields, and grow professionally in their careers.

However, the process of publishing a research paper can be challenging and time-consuming. It requires careful planning, attention to detail, and the ability to receive feedback constructively. In this blog, we outline nine steps to publish research papers successfully in high-impact journals and help researchers contribute to their fields of study.

9 Steps to Publish Research Papers Successfully

Publishing a well-written research paper can be confusing. To achieve a successful publication within a reasonable timeframe, researchers must grasp the intricacies of the publication process outlined below:

• Finalize your research topic:  A contemporary research topic, reflecting current challenges and trends in your respective field of study, is an aspect that you can seriously consider while finalizing your topic. 
• Choose the right journal and article type:  It is crucial to identify early on the most appropriate journal for your research paper. This will save considerable time and effort and increase the likelihood of its acceptance. Discussing with peers and colleagues in the field who have authored and reviewed articles will undoubtedly be helpful. Review the aims, objectives, and scope of the journal and its area of specialization to assess if your research conforms to the necessary guidelines. Consider also the peer review process, the impact factor of the journal and the time taken to publish an article. Depending on the nature of your work, also decide on the type of article relevant to your work, which may be a completely original research paper, review paper or letter, rapid or short communication. 
• Write, format, and refine your paper for submission: Even before starting to write the paper , go through the author guidelines and formatting style followed by the journal. This will make the writing process easier. Structure the article according to the type of article you are writing. Going through the published articles in the target journal will also help you in the process. A standard structure for a research paper needs to have the title, abstract, keywords, introduction, methods, results, discussion, conclusion, acknowledgements, and references. 
• Prepare required documents like a cover letter and declaration of conflicts of interest:  When you submit your manuscript, a cover letter is a must. It should highlight the central theme of your paper and the significance of your study. Further, clearly state that you comply with all basic requirements and declare any or no potential conflict of interest that could arise. 
• Check that your work is complete and submission-ready.  Read your work several times to identify any gaps and ambiguities. Review your work for innovativeness, rigour, and contribution to topical issues in the field. Seek feedback from supervisors and peers. 
• Submit your manuscript to your chosen journal : Re-check the paper to ensure that there are no errors in grammar, wording, sentence construction, or formatting and that there is consistency in formatting. Professional proofreading is important in this regard. Check if there is a logical flow of arguments and that any images or graphs used are easy to understand and clear. Ensure that all co-authors have reviewed and approved the paper for submission. 
• Tackle post-submission revisions (including peer review comments):  Nearly all papers submitted to journals undergo a peer review process, which ensures the quality of the papers published in the journal. The reviewers may provide comments and suggestions to strengthen your paper. Review the reviewer’s comments carefully and make sure to respond to each one. Aim to send your responses using the timeline given by the journal editors. 
• Revise and resubmit the manuscript (responding to peer review comments):  It is essential to approach the comments as constructive criticism. Remember to be polite and respectful in your response. Make sure to provide a detailed response on how you have addressed each comment by the reviewers. If you do not agree with any comment, always respond professionally with care; avoid getting into a personal attack. Give a detailed explanation of your arguments. Resubmit the revised manuscript highlighting all the modifications carried out based on the comments by the reviewers. Along with the manuscript, provide a letter stating the author’s responses and that they have addressed the comments by the editor and the reviewers. 
• Get accepted for journal publication:  Once the revisions are made to the satisfaction of the editor and reviewers, the paper is accepted for publication. If your paper is rejected, make the necessary revisions and send it to the journal of your second choice.

6 Important Tips on Writing a Research Paper Title

When you are searching for a research study on a particular topic, you probably notice that articles with interesting, descriptive research titles draw you in. By contrast, research paper titles that are not descriptive are usually passed over, even though you may write a good research paper with interesting contents. This shows the importance of coming up with a good title for your research paper when drafting your own manuscript.

Importance of a Research Title

The research title plays a crucial role in the research process, and its importance can be summarized as follows:

Why do Research Titles Matter?

Before we look at how to title a research paper, let’s look at a research title example that illustrates why a good research paper should have a strong title.

Imagine that you are researching meditation and nursing, and you want to find out if any studies have shown that meditation makes nurses better communicators.  You conduct a keyword search using the keywords “nursing”, “communication”, and “meditation.” You come up with results that have the following titles:

• Benefits of Meditation for the Nursing Profession: A Quantitative Investigation
• Why Mindful Nurses Make the Best Communicators
• Meditation Gurus
• Nurses on the Move: A Quantitative Report on How Meditation Can Improve Nurse Performance

All four of these research paper titles may describe very similar studies—they could even be titles for the same study! As you can see, they give very different impressions.

• Title 1 describes the topic and the method of the study but is not particularly catchy.
• Title 2 partly describes the topic, but does not give any information about the method of the study—it could simply be a theoretical or opinion piece.
• Title 3 is somewhat catchier but gives almost no information at all about the article.
• Title 4 begins with a catchy main title and is followed by a subtitle that gives information about the content and method of the study.

As we will see, Title 4 has all the characteristics of a good research title.

Characteristics of a Good Research Title

According to rhetoric scholars Hairston and Keene, making a good title for a paper involves ensuring that the title of the research accomplishes four goals as mentioned below:

• It should predict the content of the research paper .
• It should be interesting to the reader .
• It should reflect the tone of the writing .
• It should contain important keywords that will make it easier to be located during a keyword search.

Let’s return to the examples in the previous section to see how to make a research title.

As you can see in the table above, only one of the four example titles fulfills all of the criteria of a suitable research paper title.

Tips for Writing an Effective Research Paper Title

When writing a research title, you can use the four criteria listed above as a guide. Here are a few other tips you can use to make sure your title will be part of the recipe for an effective research paper :

• Make sure your research title describes (a) the topic, (b) the method, (c) the sample, and (d) the results of your study. You can use the following formula:

[ Result ]: A [ method ] study of [ topic ] among [ sample ] Example : Meditation makes nurses perform better: a qualitative study of mindfulness meditation among German nursing students

• Avoid unnecessary words and jargons. Keep the title statement as concise as possible. You want a title that will be comprehensible even to people who are not experts in your field. Check our article for a detailed list of things to avoid when writing an effective research title .
• Make sure your title is between 5 and 15 words in length.
• If you are writing a title for a university assignment or for a particular academic journal, verify that your title conforms to the standards and requirements for that outlet. For example, many journals require that titles fall under a character limit, including spaces. Many universities require that titles take a very specific form, limiting your creativity.
• Use a descriptive phrase to convey the purpose of your research efficiently.
• Most importantly, use critical keywords in the title to increase the discoverability of your article.

Resources for Further Reading

In addition to the tips above, there are many resources online that you can use to help write your research title. Here is a list of links that you may find useful as you work on creating an excellent research title:

High voltage circuit breakers are one of the core equipment in power system operation, and the voiceprint signals generated during operation contain extremely rich information. This paper proposes a fault identification method for high voltage circuit breakers based on voiceprint information data. Firstly, based on the developed voiceprint information data acquisition device, the voiceprint information of a certain high voltage circuit breaker is obtained; Secondly, an improved S-transform is proposed in the article, which generates an amplitude matrix based on the S-transform of voiceprint information; Then, through the matrix Singular value decomposition method, the fault feature quantity of voiceprint information is extracted from the time–frequency angle, and the diagnosis system of the support vector machine model is established, and the system is trained to realize the fault identification of the high-voltage circuit breaker; Finally, through experimental simulation calculations, it was shown that the accuracy of the proposed fault identification method in different operating conditions reached 92.6%, verifying the good accuracy and robustness of the proposed method and equipment.

Introduction

High-voltage circuit breakers are crucial equipment in the power system, and their operating conditions have a significant impact on the entire system, sometimes even affecting the safe and reliable operation of the entire network system 1 , 2 . Therefore, monitoring and fault identification of circuit breakers is a very important task, where circuit breaker faults generally include mechanical and non-mechanical faults. Statistics from the International Conference on Large-Scale Power Systems indicate that mechanical faults are the main type of fault, accounting for approximately 80% 3 . By acquiring the voiceprint information generated during the operation of the circuit breaker and applying fault feature extraction methods, effective monitoring of the operation status of the circuit breaker is an important means to achieve fault diagnosis of high-voltage circuit breakers. This article will conduct research in this area.

There are currently two main technical routes for the diagnosis of high-voltage circuit breaker faults: vibration signal-based and voiceprint information-based. Although there are similarities between the two routes, both require obtaining information, extracting features, and identifying features through algorithms. However, the research techniques and methods are very different, including the equipment required to collect signals, which also varies greatly. In recent years, many researchers have proposed ideas and methods for applying vibration signals of circuit breakers to achieve fault diagnosis 4 , 5 , 6 . There have been some achievements in using voiceprint information to detect faults in power systems 7 , but there are few research results on using voiceprint information to identify high-voltage circuit breaker faults. High-voltage circuit breakers contain many components with complex structures, and there is a coupling relationship between the components during the action process. Using vibration signals to diagnose faults requires high complexity in signal acquisition equipment and high requirements for the installation location and installation method of sensors. If the installation location is not selected properly, it will have a significant impact on the results, resulting in poor universality. Another technical method is to identify mechanical faults in high-voltage circuit breakers based on voiceprint information. Although it is homologous to vibration signals, it has its own advantages. The voiceprint information acquisition equipment is low in complexity, high in reliability, easy to install and use in substations, and easy to maintain, making it highly scalable. At the same time, it has high accuracy in fault identification, and its key and difficult points are mainly reflected in the acquisition, feature extraction, and classification identification of voiceprint information. This article will also study the acquisition of voiceprint information, feature extraction methods, and classification identification algorithms for high-voltage circuit breakers.

At present, many researchers have achieved many effective results in fault diagnosis of high-voltage circuit breakers. Research shows that circuit breaker fault diagnosis generally involves three main aspects: data acquisition, feature extraction, and fault diagnosis identification. In terms of time–frequency transformation, the main methods applied include Fourier transform 8 , wavelet transform 9 , chirp-z transform 10 , Hilbert transform 11 , S transform 12 , 13 , and so on. In the application of Fourier transform, as a global transformation method, Fourier transform lacks the function of time and frequency localization, and is generally suitable for analyzing stationary signals. As a windowed Fourier transform method, the length of the window function determines the temporal and frequency resolution of the signal. In addition, due to the limitations of Heisenberg's uncertainty criterion, it is difficult to obtain a good time-domain distribution and frequency-domain distribution simultaneously when using Fourier transform for time–frequency analysis of signals. Wavelet transform, as a time–frequency analysis method with variable window function, overcomes the shortcomings of Fourier transform and has the characteristic of multi-resolution analysis. However, the selection of wavelet basis functions lacks adaptability, and when using wavelet transform to analyze signals, there are shortcomings such as frequency interference, energy leakage, and boundary distortion in the time–frequency spectrum. The Chirp-z transform has improved frequency resolution compared to the Fourier transform, but it produces more low-frequency harmonics, which has a certain impact on accuracy; The Hilbert transform has high efficiency in extracting transient signals, but there are limitations on the transformation conditions. The S-transform was first proposed by Stockwell 12 , who drew on the ideas of Fourier transform and wavelet transform, and had its own advantages. The S-transform uses a variable Gaussian window function, whose width is inversely proportional to frequency, resulting in better time–frequency characteristics.

The calculation and analysis methods for fault diagnosis of high-voltage circuit breakers mainly include support vector machines 14 , 15 , wavelet analysis 9 , short-term energy analysis 16 , empirical mode decomposition 17 , information entropy 18 , transfer learning approach 19 , etc. Compared to other methods, the support vector machine method has significant advantages in dealing with small sample and nonlinear problems. It is very difficult to obtain data from high-voltage circuit breaker voiceprint monitoring, and the collected voiceprint information data has the characteristic of small sample. The support vector machine method has high potential for application in fault identification of high-voltage circuit breaker voiceprint monitoring in small sample scenarios.

This article conducts fault diagnosis research on voiceprint monitoring of high-voltage circuit breakers under different working conditions, develops a voiceprint monitoring device, and builds an experimental system to simulate different types of faults. The rest of the organization of this manuscript is as follows: Section “ High voltage circuit breaker voiceprint information data acquisition device ” explains the design and development process of the voiceprint information acquisition device. Section “ Fault feature extraction methods and application analysis ” provides a comprehensive method for extracting fault features using voiceprint information, including fault diagnosis. Section “ Experiments and analysis ” presents the analysis results of the experimental system for fault diagnosis of high-voltage circuit breakers using voiceprint monitoring information. Finally, concluding remarks are mentioned in Section “ Conclusions ”.

High voltage circuit breaker voiceprint information data acquisition device

Hardware design.

The voiceprint monitoring device mainly consists of an MSP chip, a program download interface on its left side, a chip reset circuit, three dial switches, and an external crystal oscillator circuit. Among them, in the slave sampling circuit, due to the positive power supply of the audio part's operational amplifier and the positive and negative power supply of the magnetic field part's operational amplifier, the power module of the slave is divided into two parts. One part generates a positive power supply through the MOS transistor CJ3401 and the voltage regulator BL8565 and its peripheral circuits, and the other part generates a positive and negative power supply through the voltage regulator LM27762 and its peripheral circuits.

The voiceprint sampling circuit consists of three reference voltage chips, a programmable amplification instrument amplifier AD8231ACPZ, and an operational amplifier OPA365AIDR. The principle is to convert the sound signal into an analog voltage signal that fluctuates up and down at 1.2 V through the vibration of the eardrum of the acoustic sensor (microphone sensor), and then amplify the differential voltage signal through the programmable operational amplifier AD8231ACPZ. Finally, the differential voltage signal is input to the main control chip after being reversed by the following amplifier OPA365AIDR.

Data storage card design

The SD card adopts a serial peripheral protocol working mode, and the serial peripheral protocol interface is also known as the serial peripheral interface. The serial peripheral protocol interface operates in a master–slave mode, and the master–slave connection method of the SD card is shown in Fig.  1 .

Master slave connection method.

This mode usually has one main device and one or more slave devices, and its interface includes the following four types of signals:

MOSI—Master device data output, slave device data input;

MISO—Main device data input, secondary device data output;

SCLK—Clock signal, controlled by the main device;

CS—Enable signal, controlled by the main device.

Device power supply design

Considering the application scenarios of the device, there are two methods for power supply: 1 External maintenance power supply method; 2. Built in lithium battery mode. The first scenario is suitable for continuous monitoring of a circuit breaker in intensive care (in days). The second scenario is suitable for short-term diagnostic analysis of multiple circuit breakers.

Device integration design

The online voiceprint monitoring device for the opening and closing status of high-voltage circuit breakers uses TI's MSP430FR6989 chip to process the sampling signal. As shown in Fig.  2 , the system structure diagram mainly includes MSP and its peripheral circuits, sampling circuit, positive and negative power generation module, detection circuit, LoRa wireless communication module, etc.

Structure diagram.

The main functions of the slave sampling program designed and written based on the MSP430FR6989 chip are initialization of various MSP variables, ADC sampling, timer interruption, entering the main loop, SD card data reading and writing, spectrum analysis, calculation, etc. The main program flowchart of the slave software design is shown in Fig.  3 , and the interrupt subroutine flowchart is shown in Fig.  4 .

Fault feature extraction methods and application analysis

Improved s-transformation and establishment of feature matrix.

The circuit breaker voiceprint information obtained in this study is a one-dimensional time-domain signal, and to extract its inherent features, time–frequency transformation of the voiceprint information is necessary. Generally, the transformation methods for studying time–frequency information include Fourier transform, wavelet transform, Hilbert transform, etc. Different transformation methods have different characteristics and are applicable to different scenarios. This article adopts an improved S-transform method to perform time–frequency transformation on voiceprint information.

Let the continuous time-domain signal be y ( t ), and its S-transform is represented as 12 , 13 :

where f is the frequency, φ ( δ - t , f ) is a Gaussian window function, δ is a control parameter for the position of the timeline.

From Eq. ( 2 ), it can be observed that φ ( δ − t , f ) function is a continuous function of time and frequency, with a smooth variation relationship with frequency. Its width is inversely proportional to frequency and time, providing higher frequency resolution at lower frequencies and higher time resolution at higher frequencies. Now, for the window function of Eq. ( 2 ), take the partial derivative about frequency (the frequency of the voiceprint information data of the circuit breaker studied in the article is all positive), expressed as follows:

The duration of the opening and closing sound pattern information of the circuit breaker is extremely short, at the millisecond level, and the frequency is at the kHz level. Therefore, the value of Eq. ( 3 ) is very small, close to zero, or even equal to zero. Therefore, in practical applications, when the frequency changes within a certain range, the S transformation will have insufficient energy aggregation and resolution. To address this deficiency, this article proposes an improved S transformation method, which introduces a parameter k to the window function of Eq. ( 2 ). The new window function is represented as follows:

In Eq. ( 4 ), when k  = 1, it is the same as the window function in Eq. ( 2 ). Therefore, by changing different k values, the width of the window function can be adjusted. In this paper, k  = 10 is taken. In the article, for the voiceprint information of circuit breakers, discrete time variables are collected, and the S transformation given in Eq. ( 1 ) is for continuous variables. Therefore, for the convenience of engineering application, it is necessary to change Eq. ( 1 ) and provide the S transformation expression for the discrete time series y ( n ), as shown below:

where \(y^{\prime}\left( {\frac{n}{{Nt_{0} }}} \right)\) is the discrete Fourier transform of y ( n ), t 0 represents the data acquisition interval and N represents the total number of points used.

According to the theoretical methods of Eqs. ( 5 ) and ( 6 ), and S transformation, the transformation result is a complex matrix, with rows representing different frequency values, columns representing corresponding time points, and matrix elements representing the amplitude and phase angle of the signal. Let the complex matrix of the obtained transformation result be S l × n , and the S transformation can be represented by the following equation 20 :

where \(T_{l \times n}\) is the amplitude matrix, \(\theta_{l \times n}\) is the phase matrix.

Method for extracting fault features

Regarding the method of fault feature extraction, this section adopts the mathematical idea of combining singular value decomposition and support vector machine. For matrices, singular values can characterize their inherent characteristics, have excellent stability, contain rich information 21 , and are widely used in pattern recognition, especially in extracting feature information from time–frequency matrices 22 .

For amplitude matrix B l × n , orthogonalization decomposition of the matrix can be performed, therefore, there must be two matrices L and N that satisfy the following relationship:

where L is l  ×  l matrix, N is n  ×  n matrix, C is a diagonal matrix, C   ∈   R l × n ; 0 is a zero matrix, c i is the singular value of matrix B , and p is the rank of matrix B .

According to the partitioning of the matrix, matrix B can also be represented by the following equation:

where B j is a partitioned matrix of matrix B.

Therefore, the features of the original data will be mapped onto the set of feature vectors, so that the data can still retain the feature information of the original data even in the case of dimensionality reduction. To better reflect the features of the original data after dimensionality reduction, the feature vector matrix is analyzed and processed. The feature matrix is multiplied by the sum centrality matrix (subtracting the mean of each one-dimensional feature from the original data to obtain a new matrix, which is called the centrality matrix). The new feature matrix is input into the support vector machine model for training and classification, The classification calculation method is described below.

Support vector machine classification method

When using feature identification, this article adopts the idea of support vector machine, inputting the feature vector composed of singular values into the support vector machine model, and achieving the purpose of fault identification through training.

At first, support vector machines were generally used for classification of Class 2 problems, but in practical applications, the problems were relatively complex and there were many classifications. Therefore, many improved support vector machine methods have emerged 23 , 24 . During the operation of high-voltage circuit breakers, they may operate normally or other types of faults may occur, such as normal operation, spring fatigue, spring jamming, firmware loosening, etc. The 1-v-1 support vector machine method classifies multiple operating conditions. Generally, one support vector machine can classify two types of conditions. The training and identification process is shown in Fig.  6 .

1-v-1 support vector machine identification process.

As shown in Fig.  6 , the obtained voiceprint feature vector is used as input to the 1# support vector machine. Positive samples are used to identify normal operating conditions, and then non positive samples are input to the 2# support vector machine. Positive samples identify spring fatigue, and non positive samples are further input to the 3# support vector machine. Positive samples identify spring jamming, while non positive samples indicate firmware loosening. From the calculation idea in Fig.  6 , it can be seen that the 1-v-1 support vector machine method consumes higher computational costs and has lower computational efficiency. Therefore, it is necessary to seek suitable methods for multi classification.

This article proposes an improved multi classification method based on the 1-v-1 support vector machine 25 , and applies the multi classification deep support vector machine to identify various types of faults. The structure diagram of the multi classification support vector machine is shown in Fig.  7 .

Schematic diagram of multi classification support vector machine results.

From Fig.  7 , the multi classification support vector machine establishes multiple hyperplanes, each hyperplane distinguishing a class of samples from the sample space, and ultimately completing the classification of multiple samples. The optimization problem is represented as follows 26 , 27 :

where θ d is the normal vector of the d -th classification hyperplane; \({g}_{{f}_{j}}\) is the bias term of the f j -th classification hyperplane; f j is the classification label of the sample; e is the penalty factor; \({\mu }_{j}^{d}\) is the relaxation factor; x j is the j -th sample; D is the number of hyperplanes for classification; J is the number of samples.

Based on the Lagrange theorem, establish the following function:

where \(\lambda\) , \(\eta\) is the Lagrange factor, respectively。

Using the Lagrange method, find about θ d , g d , \({\mu }_{j}^{d}\) partial derivative of Eq. ( 14 ), then it can obtain:

Substitute Eqs. ( 15 ) into ( 14 ) to obtain the dual optimization form:

where \(\lambda_{j}^{d}\) is Lagrange factor, with \(\lambda_{j} = \sum\limits_{d = 1}^{D} {\lambda_{j}^{d} }\) , \(q_{j}^{k}\) is a parameter. And \(q_{j}^{k}\)  = 1, as f j  =  d ; \(q_{j}^{k}\)  = 0, as f j  ≠  d .

From this, the decision function of the multi classification support vector machine is obtained, represented as follows:

where \(K_{j} = \sum\limits_{d = 1}^{D} {\lambda_{j}^{d} }\) .

The optimization problem of Eq. ( 11 ) is solved using the Lagrangian principle. The input of the multi classification support vector machine is the training sample set, and the output is the classification of the samples. The specific application process is as follows:

Using the singular value feature vector obtained from the previous text as input, train with Eq. ( 11 ) to establish a classification model;

Apply the Lagrange algorithm to obtain the dual form and obtain the decision function;

Determine the classification of each sample using the decision function of multi classification support vector machines.

Application analysis of fault diagnosis for high voltage circuit breakers

A comprehensive identification method for high-voltage circuit breaker faults is proposed through the improved S-transform, singular value decomposition, and support vector machine methods proposed in this article. The basic analysis flow chart of the proposed method is shown in Fig.  8 .

Circuit breaker fault identification and analysis process.

According to the method proposed in this article, the detailed implementation steps for fault diagnosis are as follows.

Step 1 Build a testing system for the voiceprint information collection architecture of a certain type of high-voltage circuit breaker. On the testing system, set various operating conditions of the circuit breaker, and then collect voiceprint information data under different conditions. Randomly compile the voiceprint information data into training data sets and validation data sets.

Step 2 Using the improved S-transform proposed in the article, time–frequency conversion is performed on different types of training data sets to obtain corresponding feature matrices.

Step 3 Perform singular value decomposition on the feature matrix to obtain the corresponding eigenvectors.

Step 4 Input feature vectors into support vector machines for training.

Step 5 After completing step 2 and step 3, the voiceprint information data in the validation dataset is input into the trained support vector machine to obtain fault diagnosis results, and then the operation status monitoring of the circuit breaker is achieved.

Experiments and analysis

Establishment of experimental system and scenario analysis.

Using the LW8-35A (T) circuit breaker as the tested circuit breaker, a test system is constructed as shown in Fig.  9 . The test system mainly includes circuit breakers, voiceprint acquisition devices, auxiliary equipment, etc.

Voice print information monitoring test system.

Manually control the opening and closing of the circuit breaker through the circuit breaker console. The sensors and software system of the monitoring device collect the voiceprint information of the circuit breaker, with a sampling frequency of 10 kHz and a collection time of 100 ms, and save it as a data file.

Fault simulation

To accurately diagnose faults, it is necessary to establish a typical fault database for high-voltage circuit breakers. When applying the device, the trained model is used to classify and identify the collected data, in order to determine the type of fault. A typical fault database for basic circuit breakers has been established through preliminary research, and actual faults will be further simulated in a laboratory environment.

The main types of faults in high-voltage circuit breakers are mechanical faults. This test mainly simulated three types of mechanical faults, including: iron core jamming, loose components, and push and pull rod jamming, as shown in Table 1 .

According to the fault settings in Table 1 , collect the voiceprint information data of circuit breaker opening and closing. Multiple fault simulation scenarios are shown in Fig.  10 . At the same time, collect the voiceprint information under normal conditions, establish a database of voiceprint information.

Fault simulation scenario.

Diagnosis results analysis

Obtain the waveform of the voiceprint information data of the circuit breaker opening and closing under different working conditions from the established experimental system, as shown in Fig.  11 .

Using the support vector machine algorithm, 15 samples were randomly selected for each working condition as the training dataset, and then 10 samples were selected as the test set. Under this training dataset and test set, the average prediction accuracy for each operating condition is obtained, as shown in Table 2 .

The calculation results in Table 2 indicate that the fault type diagnosis accuracy of the two different support vector machine methods is not the same. The multi classification support vector machine method presented in this article has improved accuracy and efficiency, and is also more convenient. By applying the calculation ideas and experimental system in this article, the overall accuracy of circuit breaker fault diagnosis has reached 92.6%, verifying the effectiveness of the monitoring device and experimental system.

In order to verify the performance of the comprehensive fault diagnosis method proposed in this article, a comparative calculation and analysis will be conducted with neural networks and decision trees. The diagnostic results will be calculated for each of the three fault types given in the article. This article evaluates the performance of different algorithms from two dimensions: accuracy of model algorithms and computation time.

The calculation results are shown in Table 3 below.

The calculation results in Table 3 indicate that the proposed comprehensive method has the best performance. The overall diagnostic accuracy of the decision tree is 83.4%, while the accuracy of the neural network is 82.5%. The worst accuracy of decision trees is 80%, and the worst accuracy of neural networks is 81%.

The average calculation time for diagnosing three types of faults using the method proposed in this article is 36.7 s, the average calculation time for decision trees is 43.5 s, and the average calculation time for neural networks is 41.9 s.

Based on the above analysis, the comprehensive diagnostic method proposed in this article has the best performance.

The calculation results under various operating conditions indicate that the comprehensive identification method proposed in this paper can effectively diagnose circuit breaker faults, verifying the feasibility and adaptability of the equipment and the proposed technical analysis method.

Conclusions

This article develops a voiceprint monitoring device for high-voltage circuit breakers. Based on voiceprint information data, a mechanical fault diagnosis method for high-voltage circuit breakers is proposed. The conclusions are as follows:

The time–frequency domain conversion and feature extraction of the opening and closing voiceprint information of high-voltage circuit breakers under different working conditions are carried out to form the original feature space, which fully describes the voiceprint characteristics.

The developed high voltage circuit breaker voiceprint information acquisition device is easy to use and has strong functionality. The built high voltage circuit breaker simulation mechanical fault diagnosis system has good adaptability and reliability, laying a certain foundation for future promotion and application.

The proposed fault comprehensive diagnosis method consisting of improved S-transform, singular value decomposition, and multi classification support vector machine can effectively extract features from the collected voiceprint information data and reliably complete fault classification diagnosis. The experimental results show that the comprehensive method has high identification accuracy and efficiency.

The test results indicate that the developed high-voltage circuit breaker voiceprint monitoring equipment and simulation test system have good application feasibility, and fault diagnosis has shown good results, providing new ideas for intelligent operation and maintenance of substations.

In future research, comprehensive fault diagnosis techniques for mechanical and non mechanical faults of high-voltage circuit breakers will be studied by obtaining voiceprint information and non voiceprint information data of circuit breakers.
