Overview
|
|
~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Dense Passage Retrieval (DPR) - is a set of tools and models for state-of-the-art open-domain Q&A research.
|
|
It is based on the following paper:
|
|
|
|
Vladimir Karpukhin, Barlas Oğuz, Sewon Min, Patrick Lewis, Ledell Wu, Sergey Edunov, Danqi Chen, Wen-tau Yih, Dense Passage Retrieval for Open-Domain Question Answering.
|
|
|
|
The abstract from the paper is the following:
|
|
|
|
*Open-domain question answering relies on efficient passage retrieval to select candidate contexts, where traditional
|
|
sparse vector space models, such as TF-IDF or BM25, are the de facto method. In this work, we show that retrieval can
|
|
be practically implemented using dense representations alone, where embeddings are learned from a small number of
|
|
questions and passages by a simple dual-encoder framework. When evaluated on a wide range of open-domain QA datasets,
|
|
our dense retriever outperforms a strong Lucene-BM25 system largely by 9%-19% absolute in terms of top-20 passage
|
|
retrieval accuracy, and helps our end-to-end QA system establish new state-of-the-art on multiple open-domain QA
|
|
benchmarks.*
