中文摘要：

根据语义网中信息拥有的属性特征以及结点之间交互方式，提出了一种信息语义信任度计算算法。信息的语义信任度定义为传播信息内容信任度和传播结点信任度两部分。每个结点通过自身本体对知识的形式化说明计算信息内容信任度；通过结点之间信息交互计算结点信任度。进而在两种计算基础上综合计算得到最终信息语义可信任度，最后通过仿真实验以及分析表明能够有效地对语义网中信息进行信任计算。

英文摘要：

A semantic trust computation algorithm of information is presented according to the attribute characteristics of information and interaction mechanism of nodes in semantic web. Semantic trust can be defined as content trust of information and the node trust between the nodes which diffuse the information. Each node computes the content trust of the information according to the formal description of knowledge provided by its own ontology. And nodes compute the node trust through the interaction of information. Then,the two former computations can be integrated into semantic trust of information. Stimulations and analyses show that the semantic trust of information can be computed effectively.
