Interesting looking project, but I just looked at the repo. UIUC is such a great school. I managed an AI team in the UIUC Research Park for two years and interactions with professors and hiring a lot of student interns was a good experience.
3 year old abandonware. What is the relevance?
Very true. The code is interesting and educational since the overall design is simple. Also true that the PDF to vector database code reminded me of something I would have done a couple of years ago. (I almost always now combine good old fashioned BM25 search with using chunk matching with embedding vectors.)
