| 中文摘要: |
| P2P信息检索的研究大多集中于资源搜索机制，而P2P存储系统是一个多结构数据存储系统，系统中有多个数据源，数据有各种表示形式，不同的用户对相同的现实世界的实体可能会使用不同的描述数据，有不同的表示，这样必然会产生语义异构的问题.首次将体裁互文性概念拓展到信息空间，设计和实现了一个基于体裁互文性的P2P信息检索模型，探讨了基本概念和性质，并以原型系统的数据为样本，对理论进行了验证.实验表明本文所设计方法在Bpref信息检索典型评价指标上取得了较好的效果。 |

| Current research for P2P information retrieval is mostly concentrated in the resource search mechanism.While P2P storage system is a multi-structured data storage system,which has multiple data sources,variety data representation.And different users may use different data to describe the same real world entity,which would induce the problem of semantic heterogeneity.This is the first to extend the concept of genre intertextuality to information space.It designed and implemented a P2P Information retrieval model based on a genre intertexuality,discussed its basic concepts and features,and the theory has been verified by the sample data in the prototype system.Experiments show that good results are achieved in the design method in bpref,which are typical evaluation indicators of P2P information retrieval. |
