【摘要】 P2P模式的文件共享系统在Internet上得到广泛应用,但在无中央服务器的纯P2P文件共享系统中,多关键词检索问题还没有得到很好解决。针对此问题,文章提出基于分布化元数据管理DMM(DistributedMetadataManagement)的P2P文件共享模型,基于模型对多关键词检索进行分析,并以资源描述框架RDF[1]和结构化纯P2P结构P-Grid[9]为基础,介绍了支持多关键词检索的P2P文件共享模型的实现。更多还原

【Abstract】 The file sharing systems based on Peer-to-Peer architecture are being rapid and wide-spread on the Internet.Unfortunately,most of the current structured P2P systems which have not any central server can not support the keywords-based retrieval.In order to resolve this problem,a file sharing model based on DMM(Distributed Metadata Man- agement) is put forwarded in this paper and keywords-based retrieval is analyzed based on the model.A proto- typing system is implemented to confirm the model’s feasibility,using RDF[1] as metadata standard and P-Grid[9] as infrastructure.更多还原
