Verb Phrase Ellipsis is a well-studied topic in theoretical linguistics but has received little attention as a computational problem. Here we propose a decomposition of the overall resolution problem into three tasks-target detection, antecedent head resolution, and antecedent boundary detection-and implement a number of computational approaches for each one. We also explore the relationships among these tasks by attempting joint learning over different combinations. Our new decomposition of
