For example, coreference resolution is a key task in natural language interfaces, machine translation, text summarization, information extraction and question answering.
information extraction systems like those built in the DARPA Message Understanding Conferences (MUC) have revealed that coreference resolution is such a crucial component of an information extraction system that a separate coreference task has been defined and evaluated in MUC-6 (1995) and MUC-7 (1998).
