ABSTRACT

The modeling and reasoning with uncertain context information is one of key problems of building context-aware applications in pervasive computing environment. In this paper, a method of modeling uncertain contexts is proposed by combining the DS theory with ontology model. Two application cases of uncertainty inference based on evidence theory are provided, and the feasibility and effectiveness of the proposed method are verified.
