Classic bag-of-words rankers such as BM25 are fast because they use inverted indexes, but they miss relevant texts that phrase things differently from the query. Dense BERT retrievers handle that vocabulary mismatch, but they depend on… 2. **[SPLADE v2: Sparse Lexical and Expansion Model for Information Retrieval](https://md.research.elamur.ai/free/en/papers/formal-2021-splade-v2-sparse-lexical/)** *(2021 · 83 citations)* First-stage retrieval needs to be both accurate and fast. Dense retrievers do well but lack explicit term matching. Learned sparse models keep the benefits of bag-of-words search, such as inverted indexes, exact matching and interpretability. This paper improves SPLADE, a sparse model that turns BERT MLM logits into… ## Co-authors here 2 co-authors with a page, the most papers together first. - [Benjamin Piwowarski](https://md.research.elamur.ai/free/en/authors/benjamin-piwowarski/) ×2 - [Thibault Formal](https://md.research.elamur.ai/free/en/authors/thibault-formal/) ×2 ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [International ACM SIGIR Conference on Research and Development in Information Retrieval (SIGIR)](https://md.research.elamur.ai/free/en/venues/international-acm-sigir-conference-on-research-and-development-in-information/): [SIGIR 2021](https://md.research.elamur.ai/free/en/venues/international-acm-sigir-conference-on-research-and-development-in-information/2021/) ## Cited by Papers of our library cite their works 190 times (of the 149,439 papers whose bibliographies we read); [33 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/stephane-clinchant/cited-by/).
