仕様書の条件文における状態遷移関係の抽出方法 Extraction method for transition relations from conditional statements in natural language requirements specifications 大西, 舞子 井, 浩也 小形, 真平 岡野, 浩三 戸次, 大介 Maiko, Onishi Hiroya, Ii Shinpei, Ogata Kozo, Okano Daisuke, Bekki ソフトウェア開発において不具合の検出を早期の工程で行うことで，手戻り作業を減らし，開発効率を上げることが一般的に知られている．自然言語の仕様書から状態遷移を抽出することで，モデル検査などの検査手法と連携を図る研究が進められており，ますます自然言語処理とソフトウェア工学の融合が欠かせなくなっている．本稿では，仕様書に現れる条件文から状態遷移関係の抽出を試みる．その中間過程として検査式へマッピング可能な時相論理式を自動生成する手法を提案し，その有用性をいくつかの実用例文で示した． In software development, it is generally known that detecting defects at an early stage of the process reduces rework and improves development efficiency. The integration of natural language processing and software engineering is becoming more important, as researches on methods to extract state transitions from natural language specifications by NLP are being conducted. In general, these approaches link NLP with formal approaches such as model checking. In this study, we attempt to extract state transition relations from conditional statements in specifications. As an intermediate process, we propose a method for automatically generating formulas of temporal logic that can be mapped to LTL formulas, and demonstrate its usefulness with some practical example sentences. technical report 情報処理学会 2021-07-01 application/pdf 研究報告ソフトウェア工学（SE） 8 2021-SE-208 1 6 2188-8825 AN10112981 https://ipsj.ixsq.nii.ac.jp/record/211808/files/IPSJ-SE21208008.pdf jpn
