Construction of Grammar Based Term Extraction Model for Japanese

In this paper we propose a grammar-based term extraction model for Japanese toward construction of multilingual term dictionary. The proposed approach evaluates termhood using morphological patterns of terms. Most of terms in Japanese consist of compound nouns or simple phrases, but detailed grammatical patterns for term extraction have not been constructed because of their complex compounding mechanisms. Applying detailed morphological investigation to Japanese compounding, we make sure their structures of word formation that can be comparable to those of Indo-European terms such as English and French.
