Semantic Data Process Method Based on RDF for Context Information

This paper suggests the optimization method of RDF Repository. When state data that occurred thing composing context information, this method processes in real-time using ontology technique in IoT environment. It needs to adapt meaning system about state to delivery correct state among different things. In other words, it is important to adapt technique to guarantee Semantic Interoperability. For this, People suggest a method such as SSNO based on ontology. However, techniques were center of modeling to express most things. They have a lack of paper about real-time reasoning engine that processes thing´s state and context. Also, ontology reasoning engine based on RDF repository currently optimized static data processing. Due to thisreason, it can not be satisfy real-time processing that request from IoT service. Therefore, thispaper research a method about optimizing RDF repository composition to solve this problem.
