Dealing with Typos for BERT-based Passage Retrieval and Ranking

Understand

Passage retrieval and ranking is a key task in open-domain question answering and information retrieval.

• Current effective approaches mostly rely on pre-trained deep language model-based retrievers and rankers.
• These methods have been shown to effectively model the semantic matching between queries and passages, also in presence of keyword mismatch, i.e.
• passages that are relevant to a query but do not contain important query keywords.
