INFORMATION PROVIDING SYSTEM AND METHOD BASED ON SERVICE USING ONTOLOGIES

摘要

A system and a method for providing an ontology-based service are provided to enable an SP and the user to find with each other freely, correctly, and easily by enabling the SP and the user to correctly register/search the service, as ontology is used for sharing meaning between the SP and the user, and the SP and the user share the ontology through a service search server. A service ontology database(140) stores the ontology indicating the service registered from the SP with more than one index keyword. A service request agent(130) receives a service request signal from the user. A service searcher determines whether the service corresponding to the service request signal is found or not by searching the ontology database. A service provider supplies the request service to the user if the service is found. A service register selects the index keyword of the service by searching the ontology registered from the SP and points an attribute value for the service of the SP. A request information transmitter transfers the attribute value for the requested service to the SP providing the searched service. A provided information transmitter receives and transmits the attribute value of the available services of the SP to the user.
