Based upon user information stored in a user information storage section, a group creation processing section 133 evaluates similarity between user attributes, and creates groups including pluralities of users being evaluated to possess mutual similarity. On the basis of this result, when access is made to a subject for access, a user suggestion processing section 135 increases recommendation points for the subject in the group to which the user belongs, by just a first number of points; and also, if an evaluation of the subject is registered, changes the recommendation points for the subject in the group, by an amount of points corresponding to the details of this evaluation registration. Based on the updated recommendation points of the subject, access subject recommendation information is transmitted to the user terminal device of each user belongs to the group. As a result, it is possible to support efficient access to the subjects that are useful to the users.
