Parker Carlson · Wentai Xie · Rohil Shah · Tao Yang
摘要
Learned sparse retrieval (LSR) is a popular method for first-stage retrieval because it combines the semantic matching of language models with efficient CPU-friendly algorithms. Previous work aggregates blocks into ''superblocks'' to quickly skip the visitation of blocks during query processing b...
