CorefQA - Coreference resolution as query-based span prediction
2020, ACL data: CoNLL-2012, GAP task: Coreference Resolution 通过QA方式处理coreference问题，A query is generated for each candidate mention using its surrounding con- text, and a span prediction module is em- ployed to extract the text spans of the corefer- ences within the document using the generated query. 近期的方法有consider all text spans in a document as potential mentions and learn to find an antecedent for each possible mention.
