How to Write an Abstract for an International Journal: A Guide for Korean Researchers

For Korean graduate students and junior faculty preparing to submit to an international peer-reviewed journal, the abstract is one of the most consequential sections of the manuscript. It's also one of the most frequently underestimated. A poorly written abstract causes many editors to reject a manuscript before the peer review process even begins. A well-written abstract gets your paper through initial screening and into the hands of reviewers who can evaluate the quality of your research on its merits.

This guide explains how to write an abstract for an international journal step by step, with attention to the specific challenges Korean-speaking researchers face when writing in English. It covers what to include, how to structure it, the language conventions international journals expect, and the most common mistakes that lead to desk rejection. For the broader fundamentals of abstract writing across document types, see our complete guide on how to write an abstract.

Quick Answer: What International Journals Expect

Six required elements. Background, purpose, methodology, results, conclusion, and keywords. All must appear, whether the abstract is structured (with labeled sections) or unstructured (a single paragraph).

Tense conventions matter. Methods and results in past tense. Conclusions in present tense. Korean tense expression maps imperfectly onto English, which makes this one of the most common error sources for Korean-authored abstracts.

The four highest-stakes mistakes for Korean researchers. Article errors (a, an, the), overlong background sections, vague results statements, and missing conclusions. All four can trigger desk rejection before the paper reaches peer review.

The fix isn't longer. International journal abstracts cap at 200 to 300 words. Korean academic writing tends to front-load extensive context, which exceeds the space available. Compress the background. Lead with the gap and the contribution.

What Is a Journal Abstract and Why Does It Matter?

A journal abstract is a self-contained summary of your entire paper, typically 150 to 300 words, that appears before the introduction. It serves several critical functions simultaneously:

  • Editorial screening. Many journal editors read only the abstract before deciding whether a manuscript is appropriate for their journal and worth sending to peer reviewers. A weak abstract often ends the manuscript's journey at the editor's desk.
  • Peer reviewer orientation. Reviewers read the abstract before reading the full paper. An abstract that clearly signals the research question, methodology, and contribution frames the reviewer's reading of everything that follows.
  • Database indexing and discoverability. Your abstract and keywords are what appear in PubMed, Web of Science, Scopus, Google Scholar, and other academic databases. Researchers who might cite your work will find it through the abstract, or not find it at all.
  • Reader triage. Researchers across your field read abstracts to decide whether a paper is worth reading in full. Your abstract determines whether your work enters the scholarly conversation or remains unread.

Step 1: Understand Your Target Journal's Abstract Requirements

Before writing a single word, read the Instructions for Authors on your target journal's website and identify exactly what it requires for abstracts. Different journals have different specifications. Submitting an abstract that doesn't conform signals to editors that you haven't read the guidelines carefully. That's a poor first impression with any editor.

The key specifications to check are:

  • Word limit. Most journals specify a maximum of 150 to 300 words. Some impose strict limits of 200 or 250 words. The limit is absolute. Exceeding it is grounds for immediate return of the manuscript.
  • Structure. Some journals require an unstructured abstract (a single paragraph). Others require a structured abstract with labeled sections, typically Background, Methods, Results, and Conclusion. Medical and health science journals (particularly those following ICMJE guidelines) almost universally require structured abstracts.
  • Tense. Some journals specify which tense to use in each section. If no guidance is given, follow the standard conventions described below.
  • Person. Most international journals prefer third-person ("The study examined...") over first-person ("We examined..."), though some, particularly in the sciences, now accept or prefer "we." Check your target journal's published abstracts to see what is standard.
  • Keywords. Most journals require a separate list of four to eight keywords following the abstract. These should be terms that researchers in your field would actually use when searching databases, not just the words that appear most frequently in your paper.

Step 2: Know the Six Elements Every Journal Abstract Must Contain

Whether your target journal requires a structured or unstructured abstract, the same core information must be present. International journals expect all six of the following elements:

1. Background and Context

One to two sentences establishing what is already known about your topic and why the gap your research addresses exists. This is not a literature review. It's the minimum context a reader needs to understand why your study was necessary. Every word counts in a 250-word abstract.

Example: "Financial risk tolerance is a critical determinant of household investment decisions, yet gender differences in the factors that predict risk tolerance have not been fully decomposed in nationally representative samples."

2. Research Purpose or Objective

One sentence stating precisely what your study set out to do. Use a clear statement of purpose: "This study examined...," "The purpose of this research was to...," or "We investigated...." Avoid vague formulations like "This study is about..." or "This paper discusses...." A clear, direct purpose statement signals to editors and reviewers that the research is focused and answerable.

Example: "The purpose of this study was to identify the factors related to financial risk tolerance among men and women using a decomposition technique applied to a nationally representative dataset."

3. Methodology

Two to three sentences describing how the study was conducted. Include the study design, data source or sample, key measures, and analytical approach. For quantitative studies, name the statistical method used. For qualitative studies, name the analytical framework. Reviewers in your field need enough methodological information to assess whether your findings are credible.

Example: "Data were drawn from the 2013 Survey of Consumer Finances, a nationally representative dataset. A full interaction model with repeated-imputation inference techniques was used to decompose gender differences in financial risk tolerance across two outcome categories: high risk tolerance and some risk tolerance."

4. Results

This is the most important part of a journal abstract and the section that receives the most attention from editors and reviewers. State your main findings specifically and concretely. Do not use vague language like "positive results were found" or "the hypothesis was supported." Name what was found. Include key statistics where the journal permits and where space allows.

Example: "Gender differences in financial risk tolerance were explained by gender differences in the individual determinants of risk tolerance rather than by gender itself. Income uncertainty and net worth moderated the relationship between gender and high risk tolerance, with income uncertainty having opposite effects on men and women."

5. Conclusion and Implications

One to two sentences interpreting what your results mean and why they matter. This is where you answer the "so what" question. What do your findings contribute to the field? What do they suggest for practice, policy, or future research? A conclusion that merely restates the results without interpreting them is a missed opportunity.

Example: "Financial fiduciaries should understand the differences in income uncertainty and net worth between men and women and how those differences relate to risk tolerance, rather than assuming gender itself is the primary driver of conservative investment behavior."

6. Keywords

List four to eight keywords after the abstract, following the journal's formatting instructions. Choose terms that are specific enough to reach the right audience but broad enough to be searchable. Use controlled vocabulary from your field's standard index (MeSH for medical research, PsycINFO thesaurus for psychology, JEL codes for economics) where applicable. Don't simply copy the most frequent words from your title. Choose terms that researchers actually use when searching for work in your area.

Step 3: Choose the Right Structure

Unstructured Abstract (Single Paragraph)

Used by most humanities, social science, and many natural science journals. All six elements appear in a single flowing paragraph. The challenge is making the paragraph coherent and readable while covering all required elements within the word limit. Each sentence must earn its place. There is no room for transitional filler.

Structured Abstract (Labeled Sections)

Required by most medical, health science, and clinical research journals. The six elements above are divided into labeled sections, typically:

  • Background (or Introduction or Purpose)
  • Methods
  • Results
  • Conclusions (or Discussion)

Some journals add additional sections such as Objective, Participants, or Implications. Always follow the exact section headings your target journal specifies. Don't substitute your own headings.

Step 4: Apply the Correct Tense Conventions

Tense in an English abstract isn't arbitrary. International journals follow specific conventions that Korean academic writers frequently get wrong because Korean tense functions differently. Here are the rules:

  • Background and context: present tense for what is generally accepted as true ("Risk tolerance influences investment decisions"), past tense for specific prior findings ("Smith (2018) found that...")
  • Purpose statement: past tense ("This study examined...") or present tense if describing a current state ("This paper reports...")
  • Methods: past tense throughout ("Data were collected from 2,246 households. Logistic regression was used to analyze...")
  • Results: past tense throughout ("The results indicated...", "A significant difference was found...")
  • Conclusion and implications: present tense for general claims and interpretations ("These findings suggest that...", "Financial advisors should consider...")

The most common tense error in Korean-authored abstracts is using present tense throughout, including in the methods and results sections. This gives the impression that the study has not yet been completed, which raises immediate concerns for editors.

Step 5: Write the Abstract Last

Write the abstract after you have completed the full manuscript. It is much easier to summarize a paper you have already written than to anticipate what a paper will contain. Many Korean researchers write the abstract first, then struggle to revise it as the paper evolves, and submit an abstract that no longer accurately represents the finished paper.

A practical approach: go through each major section of your completed manuscript and extract one key sentence. Your background section gives you the context sentence. Your introduction gives you the purpose statement. Your methods section gives you the methodological summary. Your results section gives you the key findings. Your discussion or conclusion gives you the implication sentence. Assemble these extracted sentences into a first draft of the abstract, then revise for coherence, concision, and word count.

Step 6: Check That Your Abstract Can Stand Alone

A journal abstract must be entirely self-contained. Readers encountering your abstract in a database search will not have access to the full paper. Everything they need to understand your study must be present in the abstract itself.

This means:

  • Don't refer to figures, tables, or sections of the main paper ("As shown in Figure 3...")
  • Don't use abbreviations that are not defined within the abstract itself, even if they are defined in the main text
  • Don't include citations. Abstracts do not cite references.
  • Don't use footnotes
  • Don't assume the reader has read your introduction. The abstract must provide its own context.

Common Abstract Mistakes That Lead to Desk Rejection

The following errors appear frequently in abstracts submitted by Korean researchers and are among the most common reasons for desk rejection or a request for major revision before peer review:

  • Exceeding the word limit. Abstracts that are too long are returned immediately at many journals. Count your words before submitting and cut ruthlessly if necessary.
  • Vague results statements. "The results were positive" or "the hypothesis was supported" tells an editor nothing. State specifically what was found. Specific results signal rigorous research. Vague results signal the opposite.
  • Missing the conclusion. Many Korean-authored abstracts end with the results and omit the interpretive conclusion. This reflects Korean academic conventions that prize modest, restrained closing. International journals expect you to tell them what the results mean, not just what they were.
  • Wrong tense in the methods and results sections. Using present tense for completed work ("Data are collected from...") is a significant error that signals unfamiliarity with international journal conventions.
  • Article errors. Korean has no articles. Missing or incorrect use of "a," "an," and "the" is the most pervasive language error in Korean-authored abstracts. A single paragraph with multiple article errors signals to an editor that the English language quality of the full paper may not meet the journal's standards.
  • Overly long background. Korean academic writing often front-loads context extensively before arriving at the research question, a pattern that reflects Korean rhetorical conventions but exceeds the space available in an international journal abstract. State the context in one sentence and move to the research question.
  • Passive constructions where active is expected. "It was found that..." is weaker than "The analysis revealed..." Many international journals, particularly in the sciences, now prefer active voice in abstracts. Check your target journal's published abstracts to see what is standard.
  • Subject omission. Korean permits the subject to be dropped when context makes it clear. English does not. Sentences like "Examined the relationship between X and Y" need an explicit subject ("This study examined...") in English. Subject omission is a less obvious error than article problems but appears in many Korean-authored abstracts.
  • Poor keyword selection. Keywords that are too broad ("economics," "health"), too narrow (a highly specific term no one searches for), or simply copied from the title don't serve the discoverability function keywords are meant to serve.

Language Challenges Specific to Korean-Speaking Researchers

Writing a clear, correctly formatted abstract in English is difficult for any non-native speaker, but Korean-speaking researchers face specific structural challenges that go beyond vocabulary. Korean and English organize sentences, encode grammatical relationships, and signal formality through fundamentally different mechanisms. The article errors, tense inconsistencies, and passive-to-active voice issues noted above all have roots in the structural differences between Korean and English grammar.

Korean is a Subject-Object-Verb language with a topic-comment information structure that marks the topic explicitly through grammatical particles. Korean academic writing tends to build context before introducing the main argument, reflecting Confucian academic conventions that value thorough orientation and respectful framing. Both patterns produce specific English writing tendencies in Korean-authored manuscripts: overlong backgrounds, sentences that present context before the main claim, and modesty markers in conclusions that international reviewers can read as tentative or uncertain.

Understanding the source of these patterns makes them easier to address systematically. For a detailed explanation of the most common English writing errors that arise specifically from Korean grammar structure, including articles, subject omission, relative clause placement, and countable versus uncountable nouns, read our guide to common English writing mistakes Korean speakers make.

A Model Abstract: Annotated Example

The following is a published abstract from Fisher and Yao (2017), annotated to show how each element functions:

"The purpose of this research is to explore gender differences in financial risk tolerance using a large, nationally representative dataset, the Survey of Consumer Finances. [ Purpose] The impact of the explanatory variables in the model is allowed to differ between men and women to decompose gender differences in financial risk tolerance. [ Methodology] The results indicate that gender differences in financial risk tolerance are explained by gender differences in the individual determinants of financial risk tolerance, and that the disparity does not result from gender in and of itself. [ Main finding] The individual variables that moderate the relationship between gender and high risk tolerance are income uncertainty and net worth, with income uncertainty moderating the relationship between gender and some risk tolerance. [ Specific results] Financial fiduciaries should understand the differences in income uncertainty and net worth between men and women and how those differences relate to risk tolerance." [ Conclusion and implications]

Notice what this abstract does well: the purpose is stated in the first sentence, the methodology is described concisely without technical jargon, the results are specific rather than vague, and the conclusion tells financial practitioners exactly what to do with the findings. The background context is embedded implicitly rather than stated in a separate sentence, a space-saving technique appropriate when the research context is well-established in the field.

A Checklist Before You Submit

Before submitting your abstract with your manuscript, work through this checklist:

  • Is the word count within the journal's specified limit?
  • Does the abstract include all six required elements: background, purpose, methods, results, conclusion, and keywords?
  • Is the abstract formatted as the journal requires (structured or unstructured)?
  • Are the methods and results sections written in past tense?
  • Is the conclusion written in present tense?
  • Are all articles ("a," "an," "the") used correctly?
  • Are all nouns countable or uncountable as English grammar requires?
  • Are subjects explicit in every sentence?
  • Does the abstract stand alone without reference to figures, tables, or sections of the main paper?
  • Are abbreviations defined within the abstract itself?
  • Are the keywords specific enough to reach your target audience in database searches?
  • Has the abstract been read by a native English speaker?

Professional English Editing for Korean Researchers

Even a technically strong abstract can be desk-rejected if the English language quality doesn't meet the standards of an international journal. Article errors, tense inconsistencies, preposition errors, and awkward sentence constructions are all visible in an abstract of 200 words, and editors notice them immediately. These aren't signs of insufficient effort. They're predictable consequences of writing across two of the world's most structurally different language pairs, as explained in our guide on common English writing mistakes Korean speakers make.

Editor World's English editing services for non-native speakers connect Korean researchers with native English editors who hold advanced degrees and have extensive experience preparing manuscripts for international journal submission. Every editor has passed a rigorous credentials review. 100% human editing, no AI at any stage. Your abstract and manuscript are reviewed entirely by a qualified human editor who understands both the language requirements of international journals and the conventions of academic publishing in your field.

Editor World provides a certificate of editing as an optional add-on confirming that your manuscript was reviewed by a native English speaker.

Frequently Asked Questions

How long should a journal abstract be?

Most international journals require abstracts of 150 to 300 words, with some imposing strict limits of 200 or 250 words. The limit is absolute. Exceeding it is grounds for immediate return of the manuscript without peer review at many journals. Always check the specific word limit on your target journal's Instructions for Authors page before drafting. Many Korean researchers find their first draft is significantly over the limit because Korean academic writing tends to front-load extensive background context. Cutting that context is one of the first revisions most abstracts need.

What is the difference between a structured and unstructured abstract?

An unstructured abstract presents all six required elements (background, purpose, methods, results, conclusion, keywords) in a single flowing paragraph. Most humanities, social science, and many natural science journals use this format. A structured abstract divides the same elements into labeled sections, typically Background, Methods, Results, and Conclusions. Medical and health science journals following ICMJE guidelines almost universally require structured abstracts. The information is the same in both formats. Only the visual organization differs. Always check your target journal's instructions to know which format to use.

What tense should I use in a journal abstract?

Tense in an English journal abstract follows specific conventions. Background and general claims use present tense ("Risk tolerance influences investment decisions"). Specific prior findings use past tense ("Smith (2018) found that..."). The purpose statement uses past tense ("This study examined..."). Methods use past tense throughout ("Data were collected from..."). Results use past tense ("The results indicated..."). Conclusions and implications use present tense ("These findings suggest that..."). The most common tense error in Korean-authored abstracts is using present tense throughout, including in the methods and results sections, which gives the impression that the study hasn't yet been completed.

What are the most common abstract mistakes Korean researchers make?

The most common abstract mistakes in Korean-authored manuscripts include article errors (missing or incorrect use of a, an, the), overlong background sections that exceed the word limit, vague results statements that fail to name specific findings, missing conclusions that omit the so-what interpretation, wrong tense in methods and results sections, subject omission carried over from Korean grammar, and overuse of passive constructions where international journals expect active voice. All of these have roots in the structural differences between Korean and English. Understanding the source of the patterns makes them easier to address systematically.

Should I write my abstract first or last?

Last. Write the abstract after you've completed the full manuscript. Summarizing a paper you've already written is much easier than anticipating what a paper will contain. Many Korean researchers write the abstract first, struggle to revise it as the paper evolves, and submit an abstract that no longer accurately represents the finished paper. A practical approach is to walk through the completed manuscript and extract one key sentence from each major section, then assemble those sentences into a first draft of the abstract before revising for concision and word count.

Do journal abstracts include citations?

No. Journal abstracts don't include citations or references. The abstract must be entirely self-contained. Readers encountering your abstract in a database search won't have access to the full paper, so everything they need to understand your study must be present in the abstract itself. If a point requires a citation, it probably belongs in the introduction or discussion of the main paper, not in the abstract. The same principle applies to figures and tables: the abstract shouldn't refer to anything outside itself.

How many keywords should an abstract have?

Most international journals require four to eight keywords following the abstract. The exact number varies by journal, so check the Instructions for Authors before drafting. Choose terms that researchers in your field would actually use when searching databases. Use controlled vocabulary from your field's standard index where applicable: MeSH for medical research, PsycINFO thesaurus for psychology, JEL codes for economics. Don't simply copy the most frequent words from your title. Strong keyword selection improves the discoverability of your work in databases like PubMed, Web of Science, Scopus, and Google Scholar.

How can Korean researchers improve their abstract's English?

Improving abstract English begins with understanding the structural differences between Korean and English. Article use, tense conventions, subject expression, and active versus passive voice all function differently in the two languages, which produces predictable error patterns in Korean-authored abstracts. Reading published abstracts from your target journal helps internalize the conventions of your field. Having a native English speaker review the abstract before submission catches errors that may be invisible to the writer. Professional editing services that specialize in working with Korean researchers can also identify and correct the systematic patterns that come from writing across two structurally different language pairs.
