Abstract
動詞間で共通する意味属性を考慮して,シソーラス上に整理した動詞項構造シソーラスを提案し,形容動詞まで拡張して分析を進めてきた.動詞項構造シソーラスの背景には語彙概念構造という状態変化を主に記述する形式を拡張してきたが,「必要だ」や「必ず〜する」といった主観的な内容を記述する場所が無く,意味記述の中に自然言語で埋めることになっている.本稿では述語の分析から必要となる意味構造の要件を明らかにする.その中でも可能世界意味論に関係している点を事例をもとに明確化し,文書解析のための意味構造について考察する.さらに,人工知能で議論されてきた様相論理,動的命題,設計学,オントロジー工学との関係について概観する.
Abstract Alternative
The results of our previous work of construction of Japanese verb thesaurus revealed that a verb meaning often contains not only action or change-of-state meaning, i.e., objective meaning, but subjective meanings. To describe verb meaning, lexical conceptual structure was applied, but it does not have a place of subjective and modal meaning; then they are described using natural language embedded in an extended LCS-based schema. Modal logic gives us a description framework, but verb meanings have more complex meaning, such as event attributes, progress and possibility. In the manuscript we summarize the wide variety of verb and adjective verb meaning from the view of change-of-state and subjective meaning, then discuss a description framework of them according to modal logic study.
