A Professional Freelancer's Guide on Writing Scientific Abstracts

A Scientific Abstract is probably the shortest type of a Scientific Paper there is to write. Its word count ranges from 200 to 250 words and typically consists of an introduction, an objective, a Method, Results, and a Conclusion, written out as material for Conferences, Workshops, Seminars, Congresses, and Dissertations. Most Importantly though, is that an Abstract represents a summary of an entire Article, giving Journals and readers the short but complete outlook over the whole project, while also easing the quick and easy classification of Manuscripts into Categories. These are facts that are commonly known to scientific writing freelancers who excel in the art. You should learn to keep them in mind once and for all.

Types of Scientific Abstracts

Another fact that expert writing freelancers navigate with little fuss is that every Journal, Conference, Seminar, Workshop, and Congress differ in the way they outline their requirements for an abstract. This fact makes it simple to digest clients' instructions. For your good, the following types of abstracts constitute different required formats:

1. A Structured abstract – this abstract has distinctly spelled out sections (Background, objective, methods, results, and conclusion) for readers to quickly grasp the storyline of a project without having to read the entire writing1. It usually contains between 200 and 250 words.

In consideration of the various types of scientific materials (original (research), review, and clinical practice), structured abstracts differ in form:

As advantages go, a structured abstract facilitates computerized categorizing and search, helps authors summarize their manuscripts, enables a stress-free peer-review process, and expedites assimilation.

Even though most journals require structured abstracts, there are some differences in their formats, and some journals use other structures too1. A structured abstract, for so many reasons, can be referred to as an informative abstract.

2. An unstructured abstractthis kind of material covers the various sections mentioned (or not) in a structured abstract but without parts; the writing assumes a paragraph form, the sentences describing each segment (or not). It is short and consists of between 50 and 100 words2. An unstructured abstract is akin to a descriptive summary, which lacks results and conclusions, but highlights the background and purpose of a project. So, a reader must go through the whole stuff to fully understand the methodology and outcomes. A descriptive abstract also makes it hard for peer-reviewers to assess papers quickly and renders computerization into categories a little more difficult.

3. A critical abstract – which is less popular than structured and unstructured abstracts is common in review materials. The writer gives a background, purpose, findings, and conclusions of someone else’ work and then critiques it by offering his own opinions in comparison with some other results.
