| 摘 要： | 分析并总结4大类数字图书馆资源，分别是商业数据库资源、Internet网页资源、本地自建特色资源和OAI收割元数据资源，研究不同方式的资源整合技术来实现对这几类资源的整合；在此基础上提供一系列服务，重点对统一检索服务的关键技术进行分析，并详细阐述其实现机理和工作流程。统一检索服务通过数据请求模块获取用户的检索条件实现对资源的检索，通过数据分析抽取模块进行分析抽取并存储检索结果，通过Ajax技术将检索结果动态展示给用户，以达到良好的用户体验。

| Abstract: | This paper analyzes and summarizes four types of digital library resources, including commercial database resources, Web resources, local self-built resources and OAI metadata harvesting resources, then the authors integrate these resources in different ways. Based on these resources, many services can be supplied. This paper focuses on the analysis and realization of unified search service, whose implementation mechanism and work flow are also introduced. Unified search service can achieve a good user experience by means of searching different resources through data request module, extracting data by data analyzer module, and using Ajax to show the dynamic display results to the users. |
