METHOD FOR CONTROLING ACCESS TO RESOURCE USING ONTOLOGY AND CONTEXT INFORMATION MODELING METHOD THEREFOR

摘要

PURPOSE: A resource access control method using ontology is provided to perform the modeling of context information, which is basic information for determining the access right of information resources, using the ontology. CONSTITUTION: An ontology server collects context information from a plurality of ubiquitous sensors(S201) Using the collected context information, the ontology server performs the primary ontology modeling(S203). The ontology server analyzes the primary modeling data with a predetermined rule and fact and reasons an ontology rule(S204). Using the primary modeling data and an analyzed result, the ontology server performs secondary ontology modeling(S205).
