Title Coreference Resolution with World Knowledge
Venue Annual Meeting of the Association of Computational Linguistics
Session Main Conference
Year 2011

While world knowledge has been shown to improve learning-based coreference resolvers, the improvements were typically obtained by incorporating world knowledge into a fairly weak baseline resolver. Hence, it is not clear whether these benefits can carry over to a stronger baseline. Moreover, since there has been no attempt to apply different sources of world knowledge in combination to corefer- ence resolution, it is not clear whether they of- fer complementary benefits to a resolver. We systematically compare commonly-used and under-investigated sources of world knowl- edge for coreference resolution by applying them to two learning-based coreference mod- els and evaluating them on documents anno- tated with two different annotation schemes.
