I want to create an algorithm that searches job descriptions for given words (like Java, Angular, Docker, etc). My algorithm works, but it is rather naive. For example, it cannot detect the word Java if it is contained in another word (such as JavaEE). When I check for substrings, I have the problem that, for example, Java is recognized in the word JavaScript, which I want to avoid. I could of course make an explicit case distinction here, but I'm more looking for a general solution.
Are there any particular techniques or approaches that try to solve this problem?
Unfortunately, I don't have the amount of data necessary for data-driven approaches like machine learning.
I spent some time researching my problem, and I found that identifying certain words, even if they don't match 1:1, is not a trivial problem. You could solve the problem by listing synonyms for the words you are looking for, or you could build a rule-based named entity recognition service. But that is both error-prone and maintenance-intensive.
Probably the best way to solve my problem is to build a named entity recognition service using machine learning. I am currently watching a video series that looks very promising for the given problem. --> https://www.youtube.com/playlist?list=PL2VXyKi-KpYs1bSnT8bfMFyGS-wMcjesM
I will comment on this answer when I am done with my work to give feedback to those who are facing the same problem.
