Standard pairwise coreference resolution systems are subject to errors resulting from their performing anaphora identifi- cation as an implicit part of coreference resolution. In this paper, we propose an integer linear programming (ILP) for- mulation for coreference resolution which models anaphoricity and coreference as a joint task, such that each local model in- forms the other for the final assignments. This joint ILP formulation provides f- score improvements of 3.7-5.3% over a base coreference classifier on the ACE datasets.
