Abstract: We investigate coreference relationships between NPs with the same head noun. It is relatively common in unsupervised work to assume that such pairs are coreferent– but this is not always true, especially if realistic mention detection is used. We describe the distribution of noncoreferent same-head pairs in news text, and present an unsupervised generative model which learns not to link some samehead NPs using syntactic features, improving precision.
