A relevance analysis device comprising a user specification unit (22a) for specifying an analysis reference user and an analysis target user. A server information acquisition unit (22b) acquires identification information that uniquely identifies a user, and registration information for specifying a target viewed user. A route specification unit (22c) specifies, based on the acquired information, a route constituted by continuous component routes between the user and the target viewed user. For each component route, an end-side user of the component route is registered as a target viewed user by an origin-side user. A relevance specification unit (22d) specifies the number of component routes that constitute the specified route, specifies whether the origin-side user is registered as a target viewed user by the end-side user on each of the component routes, and specifies the mutual relevance between the analysis reference user and the analysis target user. |
