Hybrid search boosts biomedical research retrieval accuracy

A project explored hybrid search methods for biomedical research, combining dense and sparse vector retrieval to improve accuracy. The experiment focused on PubMed, a challenging dataset due to its mix of plain language, specific gene symbols, mutations, and trial IDs. By comparing dense search (for meaning), sparse BM25 search (for exact terms), and a hybrid approach, the project aimed to determine the most effective way to retrieve relevant medical papers. AI
