Our system treats coreference resolution as an integer linear programming(ILP) problem. Extending Denis and Baldridge (2007) and FinkelandManning(2008)’swork,weexploit loose transitivity constraints on coreference pairs. Instead of enforcing transitivity closure constraints, which brings C7B4D2BFB5 complexity, we employ a strategy to reduce the number of constraints without large performance de- crease, i.e., eliminating coreference pairs with probability below a thresholdAI. Experimental results show that it achieves a better perfor- mance than pairwise classifiers.
