PROBLEM TO BE SOLVED: To provide an information processing device that extracts a structure having a correlation from discrete data capable of expression as a plurality of kinds of graphs.SOLUTION: A first machine identifier graph construction unit 14 is configured to receive a machine usage history OH and a machine identifier ID, let the machine identifier ID as a node and construct a first machine identifier graph Ai setting a link on the basis of the machine usage history OH. A second machine identifier graph construction unit 15 is configured to receive a machine attribute MA and the machine identifier ID, let the machine identifier ID as the node and construct a second machine identifier graph Bj setting a link on the basis of the machine attribute MA. A degree of similarity calculation unit 16 is configured to calculate a degree of similarity with respect to combinations (Ai,Bj) of all graphs in both of the machine identifier graph Ai and the machine identifier graph Bj, and a correlation relationship determination unit 17 is configured to determine presence or absence of a correlation about the combination (Ai, Bj) of each graph, respectively. |
