Abstract
The present invention relates to a method for recommending a service in a ubiquitous environment in which various services are provided, and more particularly, to a method and system for determining a service required for a user based on situation information of a target user, and recommending, to the target user, an individual service satisfying a service index of the target user with respect to the determined service, or a combined and highly complementary service.
Claims11
A combined service recommendation system comprising:
- a user information management agent for creating or storing static information, dynamic information, extended static information and extended dynamic information on a user;
- a service selection agent for selecting an individual service having the highest service index increase value among individual services provided to users having situation information similar to that of a target user from a case database based on a result of comparing a service index of the targer user with a target service index, or selecting a combined service having the highest degree of complementarity from the case database based on the degree of complementarity of combined services provided to the users having situation information similar to that of the target user;
- and
- an individual service agent for providing the target user with the individual service selected by the service selection agent or individual services configuring the combined service and managing the provided services, wherein the degree of complementarity of the combined service is calculated considering a service index increase value of the target user caused by the service combination, profits obtained from the service combination and loss of cost required for the service combination.
A combined service recommendation method comprising the steps of:
- determining a service needed for a target user based on situation information on the target user and calculating a service index with respect to the determined service for the target user from a psychosocial theory model of the determined service;
- comparing the service index of the target user with a target service index;
- selecting an individual service having the highest service index increase value among the individual services used by the users having situation information similar to the situation information on the target user from the case database if the service index of the target user is smaller than the target service index;
- selecting a combined service having the highest degree of complementarity among combined services used by the users having situation information similar to the situation information on the target user from the case database if the service index of the target user does not exceed the target service index when the individual service selected based on the service index increase value of the selected individual service is provided;
- and
- recommending the selected combined service to the target user, wherein the degree of complementarity of the combined service is calculated considering the service index increase value of the target user caused by the service combination, profits obtained from the service combination and loss of cost required for the service combination.
