In this paper, we study the impact of a group of features extracted automatically from machine-generated parse trees on coreference resolution. One focus is on designing syn- tactic features using the binding theory as the guideline to improve pronoun resolution, al- though linguistic phenomenon such as apposi- tion is also modeled. These features are ap- plied to the Arabic, Chinese and English coref- erence resolution systems and their effective- ness is evaluated on data from the Automatic Content Extraction (ACE) task. The syntactic features improve the Arabic and English sys- tems signi cantly, but play a limited role in the Chinese one. Detailed analyses are done to un- derstand the syntactic features’ impact on the three coreference systems.
