Recognizing idioms in a sentence is im- portant to sentence understanding. This paper discusses the lexical knowledge of idioms for idiom recognition. The chal- lenges are that idioms can be ambiguous between literal and idiomatic meanings, and that they can be “transformed” when expressed in a sentence. However, there has been little research on Japanese idiom recognition with its ambiguity and trans- formations taken into account. We pro- pose a set of lexical knowledge for idiom recognition. We evaluated the knowledge by measuring the performance of an idiom recognizer that exploits the knowledge. As a result, more than 90% of the idioms in a corpus are recognized with 90% accuracy.
