CG Framenet Annotation of English Television News

Beskrivelse

This talk presents the automatic semantic annotation of English television news transcripts from the UCLA Communication Studies Archive, adding verb frame categories and semantic roles on top of a morphosyntactic analysis with full dependency information. The system uses a rule-based method, where Constraint Grammar mapping rules are automatically generated from a syntactically anchored Framenet with about 500 frame types and 50 semantic role types. I will discuss design decisions concerning the Framenet, and provide some preliminary coverage and performance evaluation of the pilot system on authentic news data.
