由于知识的异构性和动态性,在网上查找知识需要花费大量的时问和精力。为了提高效率和准确性,我们提出了面向语义网的上下文知晓模型。在分析上下文、上下文知晓和TAP的概念的基础上,构建了基于TAP的上下文知晓系统的体系结构,重点阐述了上下文知晓模型。
Because of inhomogeneity and dynamics of knowledge, it spends much time and energies in querying knowledge on Web. In order to improve efficiency and accuracy, this paper presents context - aware model oriented semantic, and analyzes the concept of context ,context awareness and TAP ,and then proposes the architecture of context - aware system. The context - aware model is given more description. This paper gives a summary and points out the future work also.
