Abstract:
1. An ontology system comprising: a processor; a context broker means for receiving context information from a sensing device and verifying a validity of the received context information; a context managing means for controlling to generate an ontology structure by transforming the verified context information from the context broker means to ontology web language (OWL) data and processing the OWL data; a rule-based inference engine means for transforming the processed context information from the context managing means to semantic web rule language (SWRL) data and generating combined type information and inferred type information, wherein the combined type information is generated through processing the SWRL data using a predetermined equation, and the inferred type information is generated through processing the SWRL data by an inference process; a learning managing means for processing the processed context information from the context managing means through learning; and a database for storing the context information processed at the context managing means, the rule-based inference engine means, and the learning managing means.
