Peer-to-Peer Architectures for Federated Search of Complex Digital Libraries

摘要提案编号：iis -0240334机构：卡内基梅隆大学首席研究员：Jamie callan本提案将点对点架构方法应用于与数字图书馆联合搜索相关的问题。将大量的数字图书馆整合成一个连贯的、联合的系统是当前数字图书馆研究工作的一个基本目标和挑战。以有意义的方式进行大规模集成需要克服查询语言、资源描述和服务描述的异构性问题。点对点体系结构不同于早期的方法，后者试图通过添加具有不同模式之间转换能力的网络组件来实施单一、统一的方法。点对点体系结构的结果是取消了对单个组织的控制，但同时也增加了复杂性和拥塞的可能性。这个项目是卡内基梅隆大学和德国多特蒙德大学的研究人员共同努力的结果。

AbstractProposal Number: IIS-0240334Institution: Carnegie Mellon UniversityPrincipal Investigator: Jamie CallanThis proposal applies peer-to-peer architectural approaches to the issues associated with federated search of digital libraries. The problem of integrating large numbers of disgital libraries into a coherent, federated system is a fundamental goal and challenge for present day digital libraries research efforts. Large-scale integration in a meaningful way involves overcoming the issues of heterogeneity of query languages, resource description and service descriptons . Peer-to-peer architectures differ from earlier approaches which attempt to enforce single ,uniform approaches by adding networking components with translation capability between difference scchemas. Peer-to-peer architectures have the consequence of removing control from single organizations, but at the same time result in increased complexity and potential for congestion. This project is a coordinated effort between researchers at Carnegie Mellon University and the University of Dortmund, Germany.
