Abstract

本稿では,日本語の連体修飾節と被修飾名詞の関係を決定付ける要因についていくつかの要素を想定し,それらを用いて連体修飾節内の用言と被修飾名詞に格関係が存在するか,いわゆる内の関係であるか外の関係であるかの判別を行った.従来の手法では,主に動詞と名詞の共起関係を用いて,内の関係の可能性を調査するのみで,外の関係であるかを積極的に求めることはできなかった.本稿では,共起関係に加え,外の関係をとる度合をいくつか定義し,それらの情報を用いて判別する手法を提案する.実際の連体修飾節を用いて判別実験を行った結果,従来の格フレームを用いた手法よりも高い正解率を示すことがわかった.そして格フレームを用いた手法で出力された結果を本提案手法と統合することによって,さらなる精度向上を実現することができた.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 such as case-frames, and cooccurrence information between nouns and verbs is taken into account. Our proposed method also takes into account the information for head restrictive. In the result of experiments, we could yield higher accuracy than previous methods of using case-frames. Moreover we got higher accuracy by combining our method and case-frame method.
