摘　　要：本文在分析对等计算体系结构现状之后,提出了一种的新型P2P信息检索系统体系架构——基于聚类域的三层体系结构。该结构通过资源描述框架的元数据描述,将资源节点进行聚类,进而组成聚类域,并以此为前提和基础构建从上而下依次为应用层、结构化层和非结构化层的三层体系结构。该结构最大限度地发挥出各层结构的高效、安全优点,并相应控制了局限性和不足。This paper proposes a novel architecture of P2P based information retrieval systems： clustering domain based three-layer architecture, which is made up of application layer, structured layer and unstructured layer. The foundation of the new architecture is clustering domain having the same metadata, which is formed by nodes clustering. The sharing information is described by metadata using RDF statements. The novel architecture has inherited the advantages of both structured and unstructured architecture while eliminated their respective disadvantages.
