Combining Dependency and Constituent-based Syntactic Information for Anaphoricity Determination in Coreference Resolution

This paper systematically explores the effectiveness of dependency and constituent-based syntactic information for anaphoricity determination. In particular, this paper proposes two ways to combine dependency and constituent-based syntactic information to explore their complementary advantage. One is a dependency-driven constituent-based structured representation, and the other uses a composite kernel. Evaluation on the Automatic Content Extraction (ACE) 2003 corpus shows that dependency and constituent-based syntactic information are quite complementary and proper combination can much improve the performance of anaphoricity determination, and further improve the performance of coreference resolution.
