請求項1~7のいずれか1項に記載のデータ提供装置。 - ユーザ端末において設定された検索条件に基づく検索操作に応じて、検索条件に該当するレコードを複数含む検索結果を前記ウェブページとして該ユーザ端末に提供する場合に、前記決定手段は、レコードが検索条件に対する該当の度合いを示す検索スコアに応じて判断した前記選択傾向に基づき、前記検索結果に含まれるレコードを先読み項目として決定する、
請求項2に記載のデータ提供装置。 - ユーザ端末からのリクエストに応じてウェブページを提供するデータ提供装置におけるデータ提供方法であって、
ウェブページが提供されたユーザ端末において起こり得る事象であって、当該データ提供装置がアクセス可能な記憶手段に記憶されている情報に基づき判断可能な事象に基づき、ユーザ端末に提供される前記ウェブページに含まれる選択可能な項目のうちの少なくとも一部の項目を先読み項目として決定する決定ステップと、
前記決定ステップにおいて決定された先読み項目の選択に応じて前記ユーザ端末に送信するデータ群からなるデータセットを生成する生成ステップと、
前記ユーザ端末からの項目の選択を受け付けた場合に、前記生成ステップにおいて生成された、該項目に対応するデータセットを該ユーザ端末に送信する送信ステップと、
を有するデータ提供方法。 - コンピュータを、ユーザ端末からのリクエストに応じてウェブページを提供するデータ提供装置として機能させるためのデータ提供プログラムであって、
前記コンピュータに、
ウェブページが提供されたユーザ端末において起こり得る事象であって、当該データ提供装置がアクセス可能な記憶手段に記憶されている情報に基づき判断可能な事象に基づき、ユーザ端末に提供される前記ウェブページに含まれる選択可能な項目のうちの少なくとも一部の項目を先読み項目として決定する決定機能と、
前記決定機能により決定された先読み項目の選択に応じて前記ユーザ端末に送信するデータ群からなるデータセットを生成する生成機能と、
