"Neural Lexical Search with Learned Sparse Retrieval" - SIGIR tutorial with slides, demo, COLAB notebooks

Learned Sparse Retrieval (LSR) techniques use neural machinery to represent queries & documents as learned bags of words. In contrast with other neural retrieval techniques, such as generative retrieval and dense retrieval, LSR has been shown to be a remarkably robust, transferable, and efficient family of methods for retrieving high-quality search results
