Independent research and license usage I want to  continue working on the research I used to work on when I was in school.
The thing is that I am not a student anymore, and I also do not work for the company that works on the research project I used to work on. It used to work on the research project by myself while I was in school (a little help from professors), meaning I can probably work/project on it by myself.

My question is that since I am not in school anymore, do I need to concern the license issue as commercial? All I want to do is do my personal/individual research project and submit a work to academic purpose, such as journal or conference. I see some software or programming library I am using say "Acedemy" or "Commercial", and since this is for the academic purpose, I am not so sure which one I need to follow.
You need to read the exact terms of the licenses, and see what they call “academic” or “commercial”. There is no general definition, these types of licenses depend entirely on the software publisher.
