中文摘要:
      根据个人数字图书馆的分散性特征,将P2P(Peer to Peer)技术应用于个人数字图书馆系统,提出一种基于P2P技术的个人数字图书馆共享模型-MIPDLM,以提高个人数字图书馆共享水平。在该模型中,个人数字图书馆可根据兴趣分簇,探讨拓扑重构的过程,其基于多兴趣的搜索机制,可将搜索消息不断向兴趣相似度较高的个人数字图书馆转发,因此能大大缩小搜索范围。仿真结果表明,与随机漫步(Random Walk)机制相比,MIPDLM模型可在一定程度上提高个人数字图书馆搜索成功率,减少平均路径长度,提高资源定位效率。
英文摘要:
      A P2P technology-based personal digital library sharing model, MIPDLM, was established using the P2P technology according to the decentralized characteristics of personal digital library in order to improve the personal digital library sharing, in which the topology remodeling was studied according to the interest clusters in personal digital library. The searched messages are constantly transmitted to personal digital library with a high interest similarity, which can thus reduce the searching scope. Simulation experiment showed that MIPDLM could improve the successful searching rate, reduce the average path length, and increase the location rate of resources.
