Object display system for relatedness graph

An object display system for a relatedness graph is equipped with: an object information reception unit (102) that receives object information from a terminal device; a node conversion unit (103) that converts the object information to a corresponding node, and sets the node as a base node; a relatedness graph extraction unit (104) that extracts a relatedness graph containing that base node from a relatedness graph database (20); a node relatedness evaluation unit (105) that evaluates the relatedness of each node to a base node by using two types of evaluation index scores; an object arrangement unit (106) that converts each node to the corresponding object and arranges each object that has been converted from each node, while associating the two types of evaluation index scores (which have been produced for each node by the node relatedness evaluation unit (105)) with two-dimensional coordinates; and an object output unit (107) that outputs each object to the terminal device.
