中文摘要：

针对网络信息推荐中缺乏信任评估机制的问题,提出一种基于信任评估的信息形式化推荐方法。建立信息推荐的形式化模型,根据信息推荐中推荐源、推荐者和接收者等不同身份的节点,给出节点置信度、节点信任关系等信任评估方法,综合计算得到信息推荐路径的可信任度,在此基础上给出基于信任的信息推荐算法。实验结果证明了该方法的有效性。

英文摘要：

To solve the problem of trust evaluation mechanism for information recommending in networks,this paper proposes an information formalized recommendation method based on trust evaluation.A formalized model of information recommendation is proposed.Trust evaluation method,which is composed by node confidence and node trustable relationship,is presented according to nodes＇ different roles of information source,information recommender or information receiver.The recommendation path trust can be calculated through above trust computation.Based on trust evaluation,information recommending algorithm is proposed.Experimental results show the validity of the method.
