Challenges in Literature Sorting in Academic Research
I often hear my graduate friends complain: why do I have to organize materials again? I'm so annoyed; Or: It's Friday and I haven't finished organizing the materials yet. It's a waste of time to work on so many things, and the happy weekend plan has been ruined... There are only a lot of similar complaints, and my ears are starting to calluse when I hear them. It was also from this friend that I learned how frequent and time-consuming it is to organize literature in academic research. Whenever friends need to extract key information from a large number of scanned documents, they always feel overwhelmed. I have already put in a lot of effort into manual input, and not only has it taken time, but it is also prone to errors, seriously affecting the research progress.
Especially when preparing for a graduation thesis, the need to cite a large number of literature has become even more prominent. Therefore, I have been searching for an efficient way to help her solve this problem.
