摘要: 提出了一个适合普适计算环境的、基于本体的形式化的上下文感知模型。该模型使用本体描述语言OWL描述上下文,采用层次化的设计方法,提高了上下文表达能力和快速上下文原型。为普适计算的上下文建模和应用、上下文重用和建立面向普适计算环境的软件基础设施提供了一种可行的方法。

Abstract: This paper puts forward a formal context model based on ontology, which is suitable for pervasive computing environment. The ontology is expressed using the Web ontology language (OWL), which improves context expressing ability and rapid prototyping. The model provides a feasible method for context modeling, context application and context reuse in pervasive computing environment.
