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 . In fact , semantics plays a crucially important role in the resolution of common NPs , allowing us to identify the coreference relation between two lexically dissimilar common nouns ( e.g. , talks and negotiations ) and to eliminate George W. Bush from the list of candidate antecedents of the city , for instance .
