Abstract
Miura grammar is a Japanese grammar based on the Constructive Process Theory proposed by M.Tokieda, and developed by T.Miura. In this theory, language is composed of three processes: object, recognition and expression. These processes are combined by the law of causality. The state of an object is reflected in the speaker's recognition, and the way the speaker recognizes, the object gives rise to an expression. This paper proposes a Japanese syntactic category system (part of speech system) based on Miura grammar and formal description method of grammar rules for morphological processing, and discusses its use in Japanese morphological processing and syntactic analysis. Japanese words are classified into 400 hierarchical syntactic categories from the viewpoints of the class of the object itself and the manner of the speaker's recognition. The results of designing Japanese grammar rules for morphological processing using the proposed syntactic categories system and formal description method, show that it is easy to design and improve grammar rules, including nongeneral rules, by the proposed method. The proposed syntactic category system can be used to develop Japanese syntactic analysis, using nested structure models based on Miura grammar, without a gap between syntactic and semantic analysis.
