Abstract
Description
第2のシステム内の第2のエージェントを妥当性確認(validate)する段階と、
第2のシステム内の第2のエージェントに関する情報を第1のシステムへ転送する段階とを有する方法によって達成される。
誤って妥当性確認された誤ったエージェントによって影響を受けないという利点がある。
殆どの節(clause)は、上述のコンテンツ記述と同じ属性から作られ、例えば、
節:属性=属性値
である。
IF ジャンル=スポーツ AND サブジャンル=サッカー THEN スコア=0.65
IF 好みのチャンネル=真 THEN スコア=スコア+0.2
IF チャンネル=bbc*THEN 好みのチャンネル=真
ここで、bbc*は、全てのbbcチャンネル、即ち、bbc1,bbc2等を示しうる。
ジャンル=スポーツ,
サブジャンル=サッカー 且つ
チャンネル=bbc1
といったメディアコンテンツに関する情報と(エージェント照合アルゴリズムにより)照合される場合、結果は、
スコア=0.85(0.65に0.2を足したもの)
となり、これはこのメディアコンテンツについての結果として得られる推奨スコアである。以下、これを「スコア」と称するものとする。
・メディアコンテンツアイテムのテストセット(即ちメディアコンテンツに関する情報)を、適合性フィードバックデータベース、即ち図2中の参照番号213のデータベース、の中のデータからの、それらの対応する適合性フィードバックスコアと共に作る。
・メディアコンテンツに関する情報を取り、各エージェントにこのメディアコンテンツに対するスコアを発生させる。
・ユーザからの適合性フィードバックスコアを取り、各エージェントに対する差を計算する。
・全てのメディアコンテンツに対して最後の2つのステップを繰り返す。
・全てのエージェントに亘って平均的な差を決定する。
・各エージェントに対するパフォーマンスを決定する。
