摘　　要：本文建立了分布式情报检索系统的三种拓扑模型———检索拓扑 ,伪度量拓扑和相似性拓扑 ,并证明了检索拓扑与相似性拓扑具有一定的分布式特征 ,从而说明了这两种拓扑模型在分布式意义下的合理性。We introduce three topological models for distributed information retrieval systems:retrieval topoloy,pseudo metric topology and similarity topology,show that retrieval topological model and similarity topological model possess a certain distributed feature,and so explain the reasonableness of the two models in the distributed setting.
