摘要

An information processing system has a link information input unit, a link information totaling unit and a network similarity calculating unit. The link information input unit inputs link information indicating links among nodes in networks. The link information totaling unit totals the link information in the respective networks to be compared and determines presence/absence of the links among the nodes or link quantities. The network similarity calculating unit calculates the similarity among the networks based on the sum of the comparison results of the links among all nodes.
