| 摘 要： | 联合数字图书馆的目的就是为了实现信息的集成共享,给用户提供统一资源查询服务。提出了一种基于中介器 /包装器的联合数字图书集成信息检索机制,以RDF作为中间信息表示语言,完成查询转换和结果合成。此外描述了实现此机制的FDL集成信息检索系统,重点介绍了基于RDF的中介器、包装器产生模块的设计。并以原型系统为例,测试分析了系统性能。

| Abstract: | Federated digital library should enable heterogeneous data sources to be shared and allow users to access them easily. An integrated information retrieval mechanism for federated digital library based on mediator/wrapper was proposed. It used RDF as information exchange format, and implemented query translation and result integration. An FDL integrated information retrieval system using the mechanism was implemented. The designs of mediator and wrapper generator were introduced and the performance of the system was analyzed. |
