<cite>Ratinov and Roth (2012)</cite> extend the multi-sieve coreference model (Raghunathan et al., 2010) by identifying at most a single candidate for each mention, and incorporating high-precision attributes extracted from Wikipedia. With these restrictions, they show improvements over the state-ofthe-art on a subset of ACE mentions that are more easily aligned to Wikipedia, while our approach demonstrates improvements on the complete set of mentions including the tougher to link mentions from the transcripts.
