Abstract or annotation

It often happens that students have a problem to determine what an abstract is and what an annotation is for a bachelor’s or master’s thesis. Let’s say some basic differences together.


The annotation is basically a brief summary of several sentences (5 to 10 lines). The aim of the annotation is to briefly acquaint the reader with the issues of your bachelor’s or master’s degree. When writing an annotation, it should be borne in mind that it does not include, for example, the goal of the work, the methods used or the results obtained in the given issue.

For the annotation, its bilingual equivalent applies, ie it must be stated in English (if you write in English). Annotation is usually placed behind a solemn declaration and a separate sheet is reserved for it. Also included in the annotation are keywords whose normal range is from 3 to 8, sorted by importance.

Maybe you wonder why the annotation is created? It is simple, the summary contained in it is the basis for full-text search in professional catalogs, which is especially true for diploma and professional works that are expected to be included in the catalog.


The abstract is similar to the annotation of the content of the work. Compared to the annotation, however, it is much larger (250-500 words) and contains both the goals of the thesis and the methodology used and the results of the bachelor’s or master’s thesis. It is important to remember that the more interesting the abstract, the more likely it is for the reader to read the whole work. When formulating the abstract, we recommend using short, concise sentences and avoiding complex, unreadable formulations.

In the introduction of the abstract, it is appropriate to focus on the issues, the topic and the goal of the work. Subsequently, we describe how we dealt with the solution to the problem and how we succeeded in fulfilling the set goal with the communication of concrete results that we have reached.

The benefit is also commenting on the results, to emphasize why, as well as the entire bachelor or diploma thesis, they are useful. The abstract also includes key words that we focus on in the Bachelor’s or Master’s thesis. Official rules for writing abstracts can be found in the standards.
