基于语义扩展的P2P网络

A Semantic Expansion Based P2P overloay Network

针对当前P2P系统中多数为媒体文件,而对应描述信息有限的问题,提出了一个通过Web信息挖掘来扩展语义的算法。同时提出了一个基于语义跳表的多层环网络结构,帮助用户进行相关内容推荐。实验表明,用本文所提出的方法,在消息量很小的情况下,与传统的基于中心服务器的检索精度很相近,具有实用价值。

Since most resources in P2P network are media files which have little information of their content,we propose an approach by extracting the useful information from Web to expand the semantic vector for files and peers.Also,to improve searching process,a multi-ring semantic Skip Graph structure is proposed.From the simulation,we can see that with the low communication cost,the precision of searching is comparable with the result from the search of C/S structure network.
