Abstract

This paper presents shallow semantic parsing based only on HPSG parses. An HPSG-FrameNet map was constructed from a semantically annotated corpus, and semantic parsing was performed by mapping HPSG dependencies to FrameNet relations. The semantic parsing was evaluated in a Senseval-3 task; the results suggested that there is a high contribution of syntactic information to semantic analysis.
