摘　　要：在P2P环境下,节点面临丰富的可用资源,因此很难快速定位自己感兴趣的文件。提出了一种考虑信任的协同过滤文件推荐模型,不仅提高了推荐准确度,还提高了节点的满意度,并有效地控制了由于信任问题导致的交易失败。In the P2P environment,nodes are faced with abundant resources available, so, it is difficult for the nodes to locate the files in which they are interest. This paper puts forward a kind of collaborative filtering based file recommendation model considering the trust, which can not only improve the accuracy of recommendation but also enhances the satisfaction of nodes, and effectively control the transaction failure due to trust issues.
