One of the most important parts of a scientific research article is the abstract. Why? Because they act like advertisements for your paper. Successful authors put substantial effort into crafting their abstracts as it is often the only section of a paper that is read! And will determine whether a reader decides to continue. In the case of a conference paper, the abstract will determine whether it is accepted or not for presentation to colleagues. Conference organizers and journal editors and reviewers pay close attention to the abstract because it is a good predictor of the quality of the paper or talk. A poorly written abstract says the author is inexperienced or doesn’t care about quality.

What is the purpose of a scientific abstract?

Essentially, an abstract should reflect all the parts of your research paper, including yourself, but in shortened form. In other words, a person reading only your abstract should be able to:

• understand why you conducted the study
• how you conducted it
• what you found,
• and why your work is important.

In general, avoid the novice’s cut-and-paste approach when crafting your abstract and instead write a unique, standalone summary. Although inclusion of data is acceptable, report only those numbers that represent the most important information. Some authors include citations or URLs in their abstracts, but many journals discourage or prohibit such additions. Be sure to stay within the word limit, which most journals and conferences set for abstracts. Use Wiley Author Services to find the best journal for publication of your paper and understand their submission process for more details.  

Let’s now consider how to write an abstract. Some journals or conferences provide a template that specifies four or five sections, e.g., Background or Aim, Question, Methods, Results, and Conclusions. If so, then follow those instructions. If not, then the four-part structure provided below will serve as a basic guideline. If you follow this formula, your abstract will be well organized and will contain all the essential elements. There are four main parts in which you need to answer the following questions:

How to Write an Abstract

1. What problem did you study and why is it important?

Here, you want to provide some background to the study, the motivation behind the study, and/or the specific question or hypothesis you addressed. You may be able to set the stage with only one or two sentences, but sometimes it takes a longer description. You’ll have to use your best judgment here as to how much to say in this first section.

2. What methods did you use to study the problem?

Next, you want to give an overview of your methods. Was it a field study or a laboratory experiment? What experimental treatments were applied? Generally, you want to keep the methods section brief unless it is the focus of the paper.

3. What were your key findings?

When describing your results, strive to focus on the main finding(s) and list no more than two or three points. Also, avoid ambiguous or imprecise wording, which is a common mistake found in conference abstracts written before the data have been completely collected or analyzed. If your data are incomplete or still being analyzed, you are not ready to present your paper.

4. What did you conclude based on these findings and what are the broader implications?

The conclusions section is where you want to drive home the broader implications of your study. What is new or innovative about the findings? How do your findings affect the field of study? Are there any applications? In writing this section, however, don’t state sweeping generalizations unsupported by the data or say that insights “will be discussed”.

What other considerations should I take when writing my abstract?

Search Engine Optimization (SEO), which means including keywords people are likely to use when looking for papers on your topic. In addition to including such terms in the title and keyword field of your paper, you want to repeat those terms contextually throughout the abstract. Such repetition is used by search engines to rank an online document. By optimizing your abstract for discovery by search engines, you can raise the ranking of your paper in a search and make it easier for colleagues to find.

Some journals are now encouraging or requiring “enhanced abstracts” such as graphical abstracts or video abstracts. Although such abstracts include additional visual components, the same basic guidelines I’ve covered in this post still apply. All good abstracts recapitulate the paper and contain the four key parts listed above.

Writing good abstracts is not an art, but a learned skill. Developing such a skill takes practice. Here is an exercise to help you develop this skill. Pick a scientific article in your field. Read the paper with the abstract covered. Then try to write an abstract based on your reading. Compare your abstract to the author’s. Repeat until you feel confident. If you’ve not yet published a paper, this exercise will help you hone the skills necessary to write a concise and informative abstract.
