Learning Passage Impacts for Inverted Indexes

1 code implementation24 Apr 2021 Antonio Mallia, Omar Khattab, Nicola Tonellotto, Torsten Suel

Neural information retrieval systems typically use a cascading pipeline, in which a first-stage model retrieves a candidate set of documents and one or more subsequent stages re-rank this set using contextualized language models such as BERT.
