Excellent project. As mentioned in another comment, I've put together an embeddings database using the arxiv dataset (https://huggingface.co/NeuML/txtai-arxiv) recently. For those interested in the literature search space, a couple other projects I've worked on that may be of interest. annotateai (https://github.com/neuml/annotateai) - Annotates papers with LLMs. Supports searching the arxiv database mentioned above. paperai (https://github.com/neuml/paperai) - Semantic search and workflows for medical/scientific papers. Built on txtai (https://github.com/neuml/txtai) paperetl (https://github.com/neuml/paperetl) - ETL processes for medical and scientific papers. Supports full PDF docs.
In Show HN: I made a website to semantically search ArXiv papers
Nice project! I've spent quite a lot of time in the medical/scientific literature space. With regards to LLMs, specifically RAG, how the data is chunked is quite important. With that, I have a couple projects that might be beneficial additions. paperetl (https://github.com/neuml/paperetl) - supports parsing arXiv, PubMed and integrates with GROBID to handle parsing metadata and text from arbitrary papers. paperai (https://github.com/neuml/paperai) - builds embeddings databases of medical/scientific papers. Supports LLM prompting, semantic workflows and vector search. Built with txtai (https://github.com/neuml/txtai). While arbitrary chunking/splitting can work, I've found that integrating parsing that has knowledge of medical/scientific paper structure increases the overall accuracy and experience of downstream applications.
