近年,人工物に対する要求の高度化・複雑化に伴い,設計者に対する負担が一層増大している.以上の背景のもと,著者らは創造的設計を総合的に支援する計算機環境Universal Abduction Studio(UAS)を提案している.本稿では,設計に有用な情報をWeb情報より自動的に取得,UASで利用可能な知識表現に変換することにより,UASの設計知識データベースを効率的に拡充するための手法を提案する.

著者らは,創造的設計を支援する統合計算機環境の構築を行っている.これまでに,語彙情報をタグ付けした知識から概念類似度を基に生成される仮説的知識の有用性向上手法を提案しているが,場面に即した仮説的知識を効率的に取得するためには語彙の属性に基づくタグ付け手法とそれを用いた推論が有効である.本稿では,知識に対して語彙情報に基づく物理量をタグ付けする知識表現手法を提案し,その有効性を検証する.

本研究では創造的設計を総合的に支援する計算機環境の構築を目指している。著者らは、これまでに創造的設計を支援するための知識記述形式や推論機構、オントロジー利用の枠組みなどを提案してきた。しかしながらこれらを用いて創造的な設計を支援するためには以上の構成要素群を統合する必要がある。本稿では創造的設計を支援するための統合計算機環境を提案し、その具体的な実装構造を例示する。

設計課題に関連する領域知識を用いるだけでは,創造的な設計解を得ることは困難である.本研究では創造的設計実現のためには,設計課題に関する領域知識とそれとは異なる領域知識の統合が重要であると考え,これを総合的に支援する計算機環境の構築を目指している.本稿ではより高度な知識統合を実現するために,知識の意味的構造に基づく統合を可能とする知識表現形式とその形式に従い知識を記述するためのエディタを提案する.
