This paper proposes a dependency-driven scheme to dynamically determine the syn- tactic parse tree structure for tree ker- nel-based anaphoricity determination in coreference resolution. Given a full syntactic parse tree, it keeps the nodes and the paths related with current mention based on con- stituent dependencies from both syntactic and semantic perspectives, while removing the noisy information, eventually leading to a dependency-driven dynamic syntactic parse tree (D-DSPT). Evaluation on the ACE 2003 corpus shows that the D-DSPT out- performs all previous parse tree structures on anaphoricity determination, and that apply- ing our anaphoricity determination module in coreference resolution achieves the so far best performance.
