Abstract	画像特徴量の性質継承に基づくWebからの概念階層抽出服部峻† † 東京工科大学コンピュータサイエンス学部〒 192–0982 東京都八王子市片倉町 1404–1 E-mail: †hattori@cs.teu.ac.jp あらまし上位下位(is-a)関係や部分全体(has-a)関係といった概念階層は,様々な自然言語処理システムにとって非常に重要な基本的知識である.人海戦術的に人手で概念階層(辞書)の構築が進められている一方で,Webなどの大規模な文書データベースから自動的に知識抽出する研究も数多く行われている.後者のアプローチの一つとして, 各概念の性質として has-a関係や振る舞いを表す言語的記述をWebから抽出した上で,対象概念から下位概念候補への性質継承の度合いに基づく抽出手法を提案して来た.本稿では,既存手法のように各概念の意味的・言語的な has-a 関係の性質継承の度合いを計算するだけでなく,各概念を表す(典型)画像が持つ特徴量の性質継承の度合いを計算することによって,WebテキストだけでなくWeb画像も活用して概念階層を自動構築する手法を提案する. キーワード上位下位関係,部分全体関係,概念階層,性質継承,Webマイニング,テキスト解析,画像解析.
