Outline of Final Research Achievements

This study aims to analyze the sequences of words obtained from various materials of the Corpus of Historical Japanese (CHJ) diachronically and quantitatively. Information on grammar and semantic usage was integrated with N-gram data extracted from CHJ, and the degree of commonality of each type of material was compared and examined based on the usage of the sequence of words. It was determined that common compound words and quoted expressions were frequently used in the colloquial materials, and that the characteristics of each type of material strongly appeared in the attitudinal expression and stereotyped expressions of narratives. Furthermore, diachronic changes in the modality expressions of Japanese were examined from the viewpoint of word sequences.

Academic Significance and Societal Importance of the Research Achievements

本研究において語の連続を一律に抽出し、その一覧表を作成することにより、複合辞・連語、あるいは出現頻度の高い語の連続形式を数値に基づいて客観的に提示することが可能となった。公開された成果は、日本語史分野における複合辞・連語研究の基礎的データとなりうるものである。また、本研究は、現代語で用いられている複合辞の成り立ちや、複合辞化・連語化の理論構築、辞書の記述・古典研究・古典教育への応用にも資するものである。
