You can find a topic for your scientific article among those problems that are important and significant today. In this case, you will simultaneously solve the issue of relevance. A topic related to a particular topical issue will definitely be relevant. You also need to make sure that the work on the chosen topic will have scientific novelty, i.e. you as the author will gain some new knowledge on the subject of the study or consider the problem from a different angle.
Consider why the scientific article is being written
When choosing a topic, you need to consider the purpose for which the scientific article is being created. For example, you are writing a master's thesis and you need publications to defend it. Then you need to consider topics related to the diploma work. The number of articles for a master's thesis is not limited, but usually at least 2 are needed, so it is better to select several topics at once. The narrower and more specific their focus, the more detailed they will be.
Following the same principle, you can take a topic for a scientific article from a bachelor's thesis or coursework. If you are preparing for a conference, the topics of such events are already defined. You just need to choose a section that is closest to your specialty, and then go deeper, taking a specific direction. The same algorithm for choosing a topic is used when preparing an article for publication in scientific journals.
Take your interests into account
The easiest way to find a topic for a research paper is to base it on your own interests. But they should still fit into the field in which you work or study, although interdisciplinary research is also possible. This method is suitable for those who really enjoy doing science and who do not do it due to necessity, for example, to write an article for a master's thesis.
