Abstract

　本発明に係るデータ分類システムは、階層的な分類項目と、当該分類項目に対応するデータ群とに基づいて、当該データ群に対応する分類項目を複数選択して分類軸として出力する。該データ分類システムは、基準項目蓄積手段と、分類軸絞込手段と、優先度計算手段と、を備える。基準項目蓄積手段は、分類項目を選択するための基準項目となる分類項目群を予め蓄積する。分類軸絞込手段は、基準項目の子孫の分類項目から複数の分類項目を選択して分類軸候補とし、分類項目に対応するデータ量と、分類項目間の階層的な距離とに基づいて、計算対象となる分類軸候補を絞り込む。優先度計算手段は、前記分類軸絞込手段が絞り込んだ分類軸候補について、当該分類軸候補を表示する優先度を計算する。
