After following a rigorous literature selection, inclusion and exclusion criteria, I have finalized (around 200) research articles for my review paper. However, now I don't know how to read those papers. I tried to read a couple of articles sequentially (which obviously seems a naive approach), but I still don't know what to capture from them. I believe there should exist a systematic approach or framework to follow. PS: CS Major
You probably have some structure in mind for the review. Maybe you're doing a time-based review, wherein you start discussing work done in the 90s(say), then proceed to the next decade and so on. Or maybe your review separately addresses different aspects of the topic you're studying (say, hardware aspects, software aspects, etc.)
(There could be several other structures, based on your goals and the field.)
Once you have selected the structure, you could make folders for each of those divisions, go through the abstracts of each paper, and put then into the respective folder(s). Next, maybe you would like subdivisions within your article. Define the criteria for classifying those subdivisions, and repeat the process for each literature folder.
Once you've done this enough, you should have a fairly granular arrangement that will make your reading streamlined.
