基于共同的兴趣和需求,对等网(P2P)中的节点用户很容易形成虚拟社区。文章利用P2P网络的社区特性,通过挖掘各个层次用户的本地资源及搜索历史记录,形成跨社区路由模块和跨社区历史查询记录管理模块,使得查询首先发送到这些节点而不是相关社区的所有节点上,在此基础上提出了跨社区的P2P语义检索框架,并分析了各个功能模块的实现方法和技术,最后对未来研究进行展望。
Based on common interests and needs, node users in peer-to-peer networks (P2P) can easily form virtual communities. By exploiting the community characteristics of P2P networks and by mining local resources and search history records of users at all levels, the article constructs a cross-community routing module and a cross-community history query record management module so that queries are first sent to all nodes in these communities instead of all relevant communities , Based on which a cross-community P2P semantic retrieval framework is proposed, and the methods and techniques for implementing each functional module are analyzed. Finally, the future research is prospected.
