Coreference resolution is the task of determining linguistic expressions that refer to the same real-world entity in natural language. Research on coreference resolution in the general English domain dates back to 1960s and 1970s. However, research on coreference resolution in the clinical free text has not seen major development. The recent US government initiatives that promote the use of electronic health records (EHRs) provide opportunities to mine patient notes as more and more health care institutions adopt EHR. Our goal was to review recent advances in general purpose coreference resolution to lay the foundation for methodologies in the clinical domain, facilitated by the availability of a shared lexical resource of gold standard coreference annotations, the Ontology Development and Information Extraction (ODIE) corpus.
指代消解是指确定自然语言中指向同一实体的语言表达式的任务。一般英语领域的指代消解研究可以追溯到 20 世纪 60 年代和 70 年代。然而，临床自由文本的指代消解研究并没有取得重大进展。最近美国政府提倡使用电子病历（EHR），为挖掘患者记录提供了机会，因为越来越多的医疗机构开始采用 EHR。我们的目标是回顾一般目的指代消解的最新进展，为临床领域的方法奠定基础，这得益于可用的共享词汇资源——黄金标准指代标注集 Ontology Development and Information Extraction (ODIE) 语料库。
