Dense Passage Retrieval for Open-Domain Question Answering
Dense Passage Retrieval learns embeddings for questions and passages so relevant evidence can be found by vector similarity.
Paper & contextDanqi Chen
Combining retrieval with language understanding.
Chen studies language understanding, retrieval, and reasoning. This selection connects dense retrieval and sentence representations with more recent work on data selection, long-context models, and agents that use language to solve multi-step problems.
