An academic abstract is a short restatement of all essential points of a research paper. The abstract is one single paragraph and is subject to specific word limits, typically under 300 words.
It mirrors the structure of the paper
It is an independent document
demonstrates the paper’s organization without providing results or conclusions
gives the principal argument and summarizes the principal data, providing the reader with an overview of the objectives, methods, results and conclusions of the study
Motivation and purpose : main subject or research question and review of the relevant literature.
Specifics : problem statement, approach, objectives, hypothesis, research methodology (method(s) adopted or search strategies).
Results : main findings (proposed solutions to the problem) and discussion.
Conclusions and implications/outcomes : what the results mean and further points
The problem addressed and some background information.
The solution or insight proposed (newly observed facts).
An example that shows how it works.
An evaluation: a comparison with existing answers/techniques.
