PropBank

From Wikipedia, the free encyclopedia

PropBank is a corpus that is annotated with verbal propositions and their arguments—a "proposition bank". Although "PropBank" refers to a specific corpus produced by Martha Palmer et al.[1], the term propbank is also coming to be used as a common noun referring to any corpus that has been annotated with propositions and their arguments.

The PropBank project has been extremely influential in recent research in natural language processing. It led to wide popularity for the semantic role labelling task.

PropBank differs from FrameNet, the resource to which it is most frequently compared, in two major ways. The first is that it commits to annotating all verbs in its data. The second is that all arguments to a verb must be syntactic constituents.
