Title Coreference Semantics from Web Features
Venue Annual Meeting of the Association of Computational Linguistics
Session Main Conference
Year 2012

To address semantic ambiguities in corefer- ence resolution, we use Web n-gram features that capture a range of world knowledge in a diffuse but robust way. Specifically, we ex- ploit short-distance cues to hypernymy, se- mantic compatibility, and semantic context, as well as general lexical co-occurrence. When added to a state-of-the-art coreference base- line, our Web features give significant gains on multiple datasets (ACE 2004 and ACE 2005) and metrics (MUC and B3), resulting in the best results reported to date for the end-to-end task of coreference resolution.
