Semantic Relations between Events and their Time, Locations and Participants for Event Coreference Resolution
Agata Cybulska, Piek T. J. M. Vossen · VU Research Portal · 2013
In this study, we measure the contribution of different event components and particular semantic relations to the task of event coreference resolution.First we calculate what event times, locations and participants add to event coreference resolution.Secondly, we analyze the contribution by hyponymy and granularity within the participant component.Coreference of events is then calculated from the coreference match scores of each event component.Coreferent action candidates are accordingly filtered based on compatibility of their time, locations, or participants.We report the success rates of our experiments on a corpus annotated with coreferent events.
