Global Constraints

We consider the problem of constructing a directed acyclic graph that encodes tem- poral relations found in a text. The unit of our analysis is a temporal segment, a frag- …...

Previous work on ordering events in text has typically focused on local pairwise decisions, ignoring globally inconsistent labels. How- ever, temporal ordering is the type of domain in which global …...

We present the first work on antecedent se- lection for bridging resolution without restric- tions on anaphor or relation types. Our model integrates global constraints on top of a rich …...

We examine different features and classifiers for the categorization of opinion words into actor and speaker view. To our knowledge, this is the first comprehensive work to address sentiment views …...

AbstractDetermining the role of event arguments is a crucial subtask of event extraction. Most previous supervised models leverage costly annotations, which is not practical for open-domain applications. In this work, …...
