An efficient treatment of Japanese verb inflection for morphological analysis

要旨

Because of its simple appearance, Japanese verb inflection has never been treated seriously. In this paper we reconsider traditional lexical treatments of Japanese verb inflection, and propose a new treatment of verb inflection which uses newly devised segmenting units. We show that our proposed treatment minimizes the number of lexical entries and avoids useless segmentation. It requires 20 to 40% less chart parsing computation and it is also suitable for error correction in optical character readers.
