Analysis of Japanese relative clauses

Abstract

In this paper, we propose a new method of analyzing Japanese relative clauses. Japanese relative clause modification should be classified into at least two major semantic categories: case-slot gapping and head restrictive.In previous methods, only the information for judging a clause to be case-slot gapping, and cooccurrence information between nouns and verbs is taken into account.Our proposed method also takes into account the information for judging a clause to be head restrictive. From the result of experiments, we could find that it yielded higher accuracy than previous methods.
