Event extraction is a particularly chal- lenging information extraction task, which intends to identify and classify event triggers and arguments from raw text. In recent works, when determining event types …...

AbstractTraditional approaches to the task of ACE event extraction usually depend on manually annotated data, which is often laborious to create and limited in size. Therefore, in addition to the …...

AbstractEvent extraction is an essential yet challenging task in information extraction. Previous approaches have paid little attention to the problem of roles overlap which is a common phenomenon in practice. …...

Event detection is a fundamental task in infor- mation extraction. Most previous approaches typically view event detection as a trigger- based classification problem, focusing on us- ing syntactic dependency structure …...
