摘要
随着越来越多的资源存储到对等计算网络节点中,上层应用随之就需要底层架构提供资源定位与搜索能力.现有检索系统较难提供语义级的资源组织,且不能支持语义的资源定位和查询路由.文中把对等计算技术和语义搜索技术结合起来,以资源空间模型、本体、向量空间模型等理论研究为基础,提出了支持语义的对等信息检索模型PSRM的思想框架.
As more and more resources are stored to P2P peers, the application in upper-layer needs that the bottom-layer structure has resources locating and retrieval capabilities. The existing system is difficult to organize semantic resources and it can not support the semantic resources locating and routing. Based on the theories of resource space model, ontology, vector space model and CAN, this paper presents a P2P semantic information retrieval model PSRM.
