Abstract |
The terms coreference and anaphora tend to be used inconsistently and interchangeably in much empirically-oriented work in NLP, and this threatens to lead to incoherent analyses of texts and arbitrary loss of information. This paper discusses the role of coreference annotation in Information Extraction, focussing on the coreference scheme defined for the MUC-7 evaluation exercise. We point out deficiencies in that scheme and make some suggestions towards a new annotation philosophy. |
