A self-contained text
An abstract should be understandable without the full dissertation. State the research question, material and approach, then the main finding and its significance. Do not include information absent from the work.
Selecting content
Take the aim, method description and key findings from the final text. Rework them into a short connected passage. Simply joining sentences from different chapters often leaves repetition and inconsistent terms.
Precision and length
The University of North Carolina Writing Center distinguishes descriptive and informative abstracts. Informative abstracts include key results and conclusions. Length and contents depend on the recipient’s requirements. An article abstract is not automatically a substitute for a dissertation summary.
A practical check
Read the text to a colleague and ask them to identify the subject, method and finding. Clarify any unclear sentence. For another language, prepare key terms and separately check numbers, abbreviations and units.
A draft from four substantive answers
Answer in writing: what was studied, why, how and what was found? Connect the answers in sequence. Add material or conditions beside the method if needed to understand the result. Avoid opening with a long review of general problems.
Draft the abstract after completing the main sections so it rests on actual results. Promises about future work can otherwise remain accidentally. Reread the summary after every significant change to the conclusions.
Which results to keep
Select the result that directly answers the main question. Include secondary findings only if omitting them changes the meaning. Preserve comparison conditions and units. A number without a measure name or percentage denominator rarely helps.
In theoretical or humanities research, the result may refine a concept, classification or interpretation. State it specifically. “Features were examined” describes an action but does not explain the substantive outcome.
Shortening without losing meaning
First remove repetition between the aim and task description. Then review introductory phrases and lists that can be shortened. Do not reduce a method to an obscure abbreviation simply to save space. Check permitted abbreviations with the recipient.
Compare the shortened version sentence by sentence with the dissertation. Check for new causal explanations, recommendations or claims about scope. Brevity must not strengthen a claim. Remove a secondary detail rather than a condition essential to the conclusion’s validity.
A version in another language
Prepare key terms before translation, including methods, groups, measures and abbreviations. Use agreed spellings for names and organisations. Afterwards, check numbers, signs, units and correspondence of findings to the source.
Ask a reader familiar with the field to restate the main point from the translation. Refine wording if they understand the object or conclusion differently. Abstracts, extended summaries and dissertation summaries may have different purposes and structures. Follow the specific document’s requirements.
