| Outline of Final Research Achievements |
A Japanese semantic dictionary was developed. It is based on a formal grammar framework called Combinatory Categorial Grammar. The target domain is math problem texts. The dictionary contains 55,000 lexical entries for 8,000 surface forms. A syntactic/semantic parser based on the grammar was also developed. Furthermore, inter-sentential semantic analysis modules, such as a coreference resolution system and a discourse analysis system, were developed for generating a semantic representation of a problem including several sentences. Out-of-vocabulary words and usages can be found through automatic problem solving based on these analysis systems.
