- PropBank
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."cite journal| author=Palmer M, Kingsbury P, Gildea D |title=The Proposition Bank: An Annotated Corpus of Semantic Roles |journal=Computational Linguistics |volume=31 |issue=1 |pages=71–106 |doi=10.1162/0891201053630264 |year=2005] , the term "propbank" is also coming to be used as acommon 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.References
