Then, in reference to each previously prepared interest element with its interest element score of the user or a profile corresponding to the user, a total interest element score of the each interest element identical with each cluster representative element of the cluster is obtained as a cluster score of the cluster for every cluster; each cluster is assigned with a rank order according to the obtained score, and the clustering result is displayed according the rank order.
