Multi-Vector Retrieval as Sparse Alignment

Yujie Qian, Jinhyuk Lee, Sai Meher Karthik Duddu +5

Multi-vector retrieval models improve over single-vector dual encoders on many information retrieval tasks. In this paper, we cast the multi-vector retrieval problem as sparse alig…

Bridging the Training-Inference Gap for Dense Phrase Retrieval

Gyuwan Kim, Jinhyuk Lee, Barlas Oguz +4

Building dense retrievers requires a series of standard procedures, including training and validating neural models and creating indexes for efficient search. However, these proced…

Phrase Retrieval Learns Passage Retrieval, Too

Jinhyuk Lee, Alexander Wettig, Danqi Chen

Dense retrieval methods have shown great promise over sparse retrieval methods in a range of NLP problems. Among them, dense phrase retrieval-the most fine-grained retrieval unit-i…

Learning Dense Representations of Phrases at Scale

Jinhyuk Lee, Mujeen Sung, Jaewoo Kang +1

Open-domain question answering can be reformulated as a phrase retrieval problem, without the need for processing documents on-demand during inference (Seo et al., 2019). However,…
