Abstract

　話題語の出現数にかかわらず、ドキュメントの特徴が大きく変化した時点を特徴点として検出できるようにする。本発明では、時間情報が付与された時間情報つきドキュメントの集合を入力し、入力した時間情報つきドキュメントの集合に属する各ドキュメントに対して、各ドキュメントの特徴を示す情報を計算し、入力した時間情報つきドキュメントの集合を時間情報に基づいて分割したタイムスライス毎に、各タイムスライスに属する各ドキュメントに対して計算したドキュメントの特徴を示す情報に基づいて、各タイムスライスの特徴を示す情報を計算し、タイムスライスの特徴を示す情報の計算結果に基づいて、タイムスライスの特徴間の距離を計算し、計算したタイムスライスの特徴間の距離が予め定められた閾値を超えるタイムスライスの組を特徴点として検出する。
