In the past decade , knowledge-lean approaches have significantly influenced research in noun phrase ( NP ) coreference resolution -- the problem of determining which NPs refer to the same real-world entity in a document . In knowledge-lean approaches , coreference resolvers employ only morpho-syntactic cues as knowledge sources in the resolution process ( e.g. , Mitkov ( 1998 ) , Tetreault ( 2001 ) ) . While these approaches have been reasonably successful ( see Mitkov ( 2002 ) ) , Kehler et al. ( 2004 ) speculate that deeper linguistic knowledge needs to be made available to resolvers in order to reach the next level of performance .
