Relevance analysis device, relevance analysis method, and relevance analysis program

摘要

Relevance analysis devices, methods, and programs analyze a mutual relevance between a plurality of users utilizing a server that allows users to view information provided by target viewed users. The devices, methods, and programs specify an analysis reference user and an analysis target user. The devices, methods, and programs specify a route that spans between the analysis reference user and the target viewed user, and specify a mutual relevance between the analysis reference user and the analysis target user based on a number of component routes that make up the specified route and based on a number of the component routes in which an origin-side user is registered as a target viewed user by an end-side user.
