CORRELATION RULE COMPARISON METHOD, CORRELATION RULE COMPARISON DEVICE, AND CORRELATION RULE COMPARISON PROGRAM

摘要

PPROBLEM TO BE SOLVED: To visually display correlation rules extracted from a plurality of data groups so that similarity relations among a plurality of correlation rules can be easily found out. PSOLUTION: In a correlation rule comparison method performed by a correlation rule comparison device including a correlation rule extraction means, a match flag giving means, a score giving means, and a correlation rule display means, the correlation rule extraction means extracts correlation rules from data D respectively, and the match flag giving means gives match flags showing matching or non-matching with the extracted correlation rules, to data di (i=1, 2, ..., n) of data D, and the score giving means gives scores to correlation rules on the basis of the given match flags so that similar correlation rules have values approximating to each other, and the correlation rule display means displays correlation rules on coordinates with the given scores as coordinate values to visualize similarity relations of correlation rules.
