Summary:To provide an information processing apparatus which allows generation of a universal rule that enhances accuracy of a prediction result as compared with a case in which a model of predicting a result based on an event item and a value of the event item is simply applied.SOLUTION: Reception means of an information processing apparatus receives event data having a plurality of event items and values and results of the event items. Model generating means generates a model having a tree structure formed by combining the event items with the values of the event items. When a concordance rate of a result obtained by applying the event items and the values of the event items to the model and a result of the event item and the value of the event item are equal to or larger than a predetermined ratio, extracting means extracts, as a rule candidate, a combination of the event item in the tree and the value of the event item. Universal rule generating means generates a universal rule from a plurality of rule candidates.SELECTED DRAWING: Figure 1 【課題】事象項目とその事象項目の値とから結果を予測するモデルを、単に適用する場合に比べて、予測する結果の精度を高めることができる汎用的なルールを生成することができる情報処理装置を提供する。【解決手段】情報処理装置の受付手段は、複数の事象項目と該事象項目の値と結果を有する事象データを受け付け、モデル生成手段は、前記事象項目と該事象項目の値を組み合わせたツリー構造を持つモデルを生成し、抽出手段は、前記モデルに対し事象項目と該事象項目の値を適用して得られる結果と、該事象項目と該事象項目の値における結果との一致率が予め定められた割合より大又は以上である場合、前記ツリー中の事象項目と該事象項目の値との組み合わせをルール候補として抽出し、汎用ルール生成手段は、複数のルール候補から汎用的なルールを生成する。【選択図】図1
