Abstract

This paper proposes a method of extracting metonymic expressions and their interpretative expressions from corpora and its application for the full-parsing-based matching method of a QA system. An evaluation showed that 79% of the extracted interpretations were correct, and an experiment using testsets indicated that introducing the metonymic expressions significantly improved the performance.
