POTENTIAL TARGET DERIVING DEVICE, POTENTIAL TARGET DERIVING METHOD, AND ITS PROGRAM

摘要

PROBLEM TO BE SOLVED: To derive a more precise potential target by combining sequence analysis with decision tree analysis in a data mining technology.

SOLUTION: Time-sequential attribute data are inputted, and a rule specific to an attribute data appearance group is selected from a sequence analysis result, and the data are worked into data which are equipped with the same time-sequential transition as a rule in positive correlation with the specific attribute data appearance inclination and data which are not equipped with the same time-sequential transition as a rule in negative correlation with the specific attribute data appearance inclination. Also, data other than the time-sequential data are added, if necessary. Thus, features whose appearance rate is high are extracted, only for the specific attribute data appearance group by decision tree analysis so that a potential target is derived.
