In the past in natural language processing (NLP), many attempts have been made to extract idiosyncratic multiword expressions (MWEs) such as idioms, quasi-idioms, cliches, quasi-cliches, institutionalized phrases, from corpora and construct a lexicon of them. However, no extensive, reliable solution has yet been realized. This paper presents an overview of a comprehensive lexicon of Japanese multiword expressions (Japanese MWE Lexicon: JMWEL), which has been compiled in order to realize linguistically precise and wide-coverage natural Japanese processing systems. The JMWEL is characterized by significant notational, syntactic, and semantic diversity as well as a detailed description of the syntactic functions, structures, and flexibilities of Japanese MWEs.
