CLUSTERING PROGRAM, CLUSTERING METHOD, AND CLUSTERING DEVICE

摘要

PROBLEM TO BE SOLVED: To facilitate analysis of tendency of consumers' purchasing behaviors.SOLUTION: A clustering device 100 compares purchase history information of each of a plurality of consumers in a first period and purchase history information of each of a plurality of consumers in a second period, and determines information indicating a difference of the number of purchases in the second period relative to the first period regarding each commodity purchased in at least either one of the two periods as clustering feature information for each consumer identification information. The clustering device 100 creates a plurality of purchase groups Gz1 to Gzn (n≥2) by performing clustering processing based on the feature information identifier for each consumer identification information.
