摘　　要：语义Web提供了实现对Web异构信息源智能访问和处理的平台。然而在语义Web上分布着海量知识,如何在这些海量知识中按照用户的需求快速准确的定位目标知识已成为语义Web迫切需要解决的问题。针对此问题,文章提出了一种知晓内容和上下文的语义Web知识路由机制。该机制采用基于本体和概念格的推理技术,通过捕捉用户需求内容和上下文等语义信息,能够快速准确地实现目标知识与服务的发现、定位、访问以及初步评估。The Semantic Web provides the intelligent access to the distributed and heterogeneous information resources. But there is abundant knowledge in the Semantic Web.How to effectively manage this knowledge and acquire accurate and effective knowledge is the critical issue in the Semantic Web.This paper focuses on this issue and proposes a content-aware and context-aware knowledge routing mechanism,which, is implemented based on the ontology and concept-lattice technique.At last,this paper gives a detail introduction of the working process of the content-aware and context-aware knowledge routing mechanism on the instance of traveling and shows the development of our experimental system.The conclusion and future work will also be discussed in this paper.
