The present invention provides a user profile which takes a user's situation into consideration. A management device 100 creates, in response to a request from applications 110, a new user profile (hereinafter referred to as “comprehensive user profile”) based on a plurality of user profiles, and provides it to the applications 110. The management device 100 always monitors a user's situation, directly or indirectly correlates the user's situation at the time that the user profile is registered with the user profile, and stores the same. Because the management device creates the comprehensive user profile based on the user profile corresponding to the current user situation, the comprehensive user profile reflects the user's situation which changes from time to time.
