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… ## All works 3 works of theirs in our library, the most cited first; 2 with a page here, the others link their original until we summarise them. 1. **[SPLADE: Sparse Lexical and Expansion Model for First Stage Ranking](https://md.research.elamur.ai/free/en/papers/formal-2021-splade-sparse-lexical-expansion/) [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/)**Thibault Formal, Benjamin Piwowarski, Stéphane Clinchant*2021 · 512 citations* 2.
