Abstract

特許の内容を記述する「特許明細書」において最も重要な箇所は、「特許請求項」(クレーム)の部分である。特許請求項は、1文で発明内容を記述するという制約と、その独特の記述形式により、専門家以外の人にとっては極めて読みにくいものになっているのが通例である。我々は、特許請求項の可読性を向上させることを目的とした、言語処理技術の研究を行っている。特許請求項の記述内容をわかりやすく提示するためにはまず、その構造を解明することが必要である。特許請求項の記述ではいくつかの定型的な表現が多用されており、それらが請求項の構造解明の手がかりとなることがわかった。こうした手がかり句を利用して特許請求項の修辞構造を解析する手法について提案し、その現時点での評価結果について報告する。The most important part of patent specification documents is patent claims. It is common that claims written in Japanese are described in one sentence with peculiar style and are difficult to understand for ordinary people. We are investigating NLP technologies to improve readability of patent claims. It is necessary to analyze the structure of patent claims so that they can be presented in readable ways. We found that there are several typical phrases used in claim descrip-tions and that they can be used as clues to analyze claim structure. We propose a method to analyze rhetorical structure of patent claims by using these cue phrases and report the result of its evaluation at this point.
