Classification of scientific articles helps to structure a large number of studies and categorize them. There are several main categories, each of which serves a specific scientific purpose and forms a different contribution to the scientific community. Today let's look at the main types of articles, their structure and differences.

All types of research articles can be categorized according to the main types:
Original research
The most common type of article that is based on the author's own research. Research articles are highly valued in the scientific community, as these are the primary source of new knowledge and discoveries. Original research is the link between discoveries in the laboratory or other settings and the scientific community. Writing such a paper requires a lot of time and resources, this should be considered before opting for this type of research.
Review paper
This type of research is a good start for scientific activity. The article provides a comprehensive analysis of already existing scientific literature in a certain field of knowledge. The main purpose of this type of scientific papers is to highlight problems for future research based on a comprehensive analysis and synthesis of published materials and data. There are 3 types of review articles: meta-analyses, systematic reviews and literature reviews.
High-quality, objective articles with an in-depth review of a particular field of knowledge are also highly valued in the academic community and are often characterized by a large number of citations.
Experimental article
Such an article is based on experiment as the main engine of scientific progress. An experimental article is a special type of research in which theory meets practice. This scientific publication presents new data obtained as a result of experimentation. The special value of such a paper is the opportunity to practically test a hypothesis, confirm an existing theory or, conversely, make a refutation of such. An experimental paper is more than a description of the experiment conducted. For qualitative research, it is important to correctly apply statistical methods of analysis and correctly interpret the results obtained.
Methodology paper
A basic scientific paper describing new methods and/or tools for conducting scientific research. The main purpose of such articles is to develop new research methods or suggest ways to improve existing ones. Methodological articles are a particularly valuable category of research papers that provide scientists with tools and ways to achieve accurate results that can be replicated.
Review article
A review article or perspective article is a popular type of scientific publication in which the author expresses his or her opinion on some aspect of research. Perspective articles do not require original research, as well as the preparation of scientific materials in a large volume. As a rule, these are short articles (no more than 2000 characters without spaces). Nevertheless, this research paper requires deep knowledge in the field of science. Researchers with extensive experience in a particular field of study are usually hired to write review articles.
Case studies
A case study is a detailed study of one or more individual cases. Such research papers are a more highly specialized approach to a research topic, allowing researchers to focus on specific cases or events. A case study is a unique tool that allows a case of interest to be isolated into a separate study.
Structure and differences between different types of research papers

Type of scientific paper |
Mandatory structure |
Main differences |
|
Original research |
|
Based on the original research, contains new data, ideas, methods, original results. Research articles are the basis for academic discussions and new work in a given field of knowledge. |
|
Review article |
|
Implies a comprehensive in-depth analysis of the published scientific literature. The main purpose of review articles is to make recommendations and identify problems for future research. |
|
Experimental article |
|
The scientific publication is based on the results of experimental research conducted by the author. The key aspects are the methodology used to conduct the experiment and the detailed analysis of the obtained data. |
|
Methodology paper |
|
Offers scientists from different fields new methods and tools for research, their detailed description and application in scientific work. Ensures high quality and standardization of scientific papers. |
|
Article review |
|
Instead of comprehensively analyzing published research, the author of a perspective article offers his or her own perspective on concepts taken from the research. Such articles are considered secondary scientific literature. |
|
Case study |
|
This type of research allows you to focus on a specific case/event/problem within a single topic. More detailed and in-depth analysis of a specific case. |
Classification of scientific articles helps you to better navigate the scientific literature, choose the appropriate type of research for potential research papers, and effectively analyze published papers.
