摘要：
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 D-S theory with ontology model. And also an improved evidences combination rule is presented not only to solve the D-S theory limitations in the case of high-degree conflict evidences but also to make the reasoning have self-adaptability. Then the uncertain reasoning algorithm is designed and implemented. Finally, the feasibility, rationality and effectiveness of this approach are verified through an e-health use case of the prototype system.
