对等网信息检索的研究现状与展望

随着对等网(P2P)研完的进一步深入以及P2P网络中Peer结点和共享文件的进一步增多，如何在非集中式的P2P网络中发现所需要的文件已经成为P2P从研究走向实用的关键所在。该文首先提出了P2P挖掘的概念，然后指出P2P信息检索作为P2P挖掘中的一部分，已经成为P2P研究的一个热点。接下来提出了P2P网络的路由、搜索、挖掘的框架模型，指明了该领域研究的框架。然后分层综述了P2P信息检索的进展状况，对各种检索方法做了深入分析。并指出了它们各自的优缺点和应用局限性，最后对今后的P2P信息检索领域的发展方向进行了展望。

A Survery and Prospects of Information Retrieval on the Peer-to-Peer Network

With the furthe development of the Peer-to-Peer research and the increase in the peer number and the documents published by peers in P2P network,how to retrieve the needed information in the P2P network is becoming more and more important. In the beginning of the paper the Pming(P2P Mining) concept has been proposed,and next this paper indicates that as a part of PMining,P2P Information Retreval(P2P IR)has been becoming a new research field. Next,a P2P routing,retrieval and mining model, which gives the research frame in P2P IR.is proposed. Next we review the development to P2P IR techniques- The characteristics of the P2P IR methods are analyzed; and the advantages,disadvantages and applied limitations are pointed out. Finally,the future direction in this field is discussed-
