Abstract: The invention aims to provide a relationship evaluation system capable of effectively evaluating a relationship of a node to a reference node in a relationship graph in which plural nodes are connected by links. A reference point node is selected based on selection information regarding the reference point node input from the selection information input unit. Based on the reference point node, a relationship graph becoming an evaluation target is extracted from the relationship graph database to create a virtual communication network based on the graph. In the virtual communication network, simulation is executed by sequentially propagating a virtual communication packet to adjacent nodes from a reference point node selected by the reference point node selection unit as propagation origin. The relationship of the node to the reference node is evaluated based on the content of the communication packet received at the node as a result of executing the simulation.

Abstract: A relationship graph interlinkage system includes a plurality of relationship graph databases 20 which stores a plurality of relationship graphs respectively, a selected information acceptance unit 101 which accepts selected information from a terminal device 40 via a computer network, a relationship graph selection unit 102 which selects a plurality of the relationship graphs from the relationship graph databases based on the selected information, a relationship graph evaluation unit 103 which evaluates each relationship graph by measuring a parameter of the node contained in each relationship graph, a parameter evaluation unit 104 which evaluates the parameter of the node contained in each relationship graph evaluated by the relationship graph evaluation unit 103, an output node determination unit 105 which determines node to be output to a terminal device via a computer network based on a result of evaluation of the parameter by the parameter evaluation unit 104.
