Abstract: Aiming at the problem that the P2P system lacks effective information search mechanism, a non-structural P2P search mechanism based on peer interests is introduced. By digging out the peer interests, and forming a network according to the relevancy that they display, peer interests with high relevancy are close in the network. When searching information in P2P network, information search is routed to peers of relevant interests, so that searc efficiency is promoted.

摘要： 针对P2P系统缺乏有效信息搜索机制的问题，提出一种基于节点兴趣的非结构化P2P搜索机制。通过挖掘每个节点的兴趣，将节点按照其相关性组成网络，使相关性高的节点在网络中距离较近。在P2P网络中进行信息搜索时，只将查询消息路由到相关兴趣的节点上，以改善搜索效率。
