基于本体的上下文推理技术应用

ontext Reasoning is that inferences high level context information from low level context information,rich types of context information and meet the needs of application.This paper first analyze the modeling methods and reasoning methods ,then analyze the Jena inference mechanism.Finally,as an example of Smart Home,by constructing a Ontology based Smart Home model,definiting reasoning rules,using Jena inference engine to reason,verify the availability of context reasoning.
