Pattern Based Term Extraction Using ACABIT System

In this paper, we proposed pattern based term extraction model for Japanese applying ACABIT system developed for French. Proposed model evaluates termhood using morphological patterns of basic terms and term variants. After extracting term selections, ACABIT system filters non-terms out from the selections based on simple log likely hood evaluation. This approach would be suitable to Japanese term extraction because most of Japanese terms form compound nouns or simple phrasal patterns. After showing the morphological patterns for terms, we show experimental results. By comparing morphological patterns with foreign languages, we discuss morphological units in Japanese.
