Abstract

A related information presentation device is designed to communicate client terminals so as to search and present users with useful content information unanticipated by users with reference to a plurality of indirectly related content information which is not directly related to each other but which is assumed to be indirectly related to each other through the same relevant content information. Upon receiving a search expression input by each user of a client terminal, the related information presentation device searches specific content information so as to automatically extract indirectly related content information, correlated to the specific content information, from among a plurality of indirectly related content information. Subsequently, the related information presentation device generates display data representing a graph connecting between a node representing the specific content information and a node representing the indirectly related content information via an edge, thus transmitting the display data to the client terminal.
