The Research Of Context-Aware System Based On Semantic Web

With the research of Smart Home (Intelligence Space), the realization has also get widespread concern and the pervasive computing is an important technology. Context-aware technology and the construction of the context-aware systems is the key to realize the pervasive computing. By using the semantic web technology in the context-aware systems construction and context information expression, the ontology-based context can be shared among the entities and information interoperability, information reasoning.This paper research the construction and realization of context-aware based on semantic web technology. First, make a introduction of the technology of pervasive computing and context awareness; then analyze the semantic web and related reasoning engine technology, and make a detailed analysis of context-aware system based on semantic web technology, the structure, each part of the functions, contextual ontology construction and reasoning, and finally bring out outlook and summary.The paper makes a research in the construction and realization of context-aware system based on semantic web technology, design an intelligent health care scenario. At first, the paper make an introduction of the technology of pervasive computing and context awareness; then analyze the semantic web and related reasoning engine technology, and make a detailed analysis of context-aware system based on semantic web technology, the structure, each part of the functions, contextual ontology construction and context reasoning, design an intelligent medical system, analyze the context ontology's construction of the system.The main achievements of this paper is to make a deep research of context-aware system which is based on semantic web technology, and use the semantic web ontology to realize the context modeling and context reasoning, so as to provide a mechanism to provide high-level context for the application. The paper also designs a simulated scenario to achieve the context-aware system.
