中文摘要：

语义检索作为语义网技术的一部分，逐渐成为信息检索领域的重要研究对象。语义聚合环境下，数字图书馆语义检索具有以下特点：利用基于资源深度聚合的OSI开放式协议，综合利用多种语义聚合方法，综合利用多种语义互联技术。就总体趋势而言，数字图书馆语义检索从功能上可以划分为面向服务的聚合与检索、面向用户的聚合与检索、面向知识推理与知识创新的聚合与检索。

英文摘要：

As a part of semantic web technologies, the semantic retrieval has become the important object of study in the field of the information retrieval. Under the semantic aggregation environment, the semantic retrieval of digital libraries has following characteristics： the use of OSI open protocol based on the resource depth aggregation, the comprehensive utilization of semantic aggregation methods, and the comprehensive utilization of a variety of semantic interconnection technologies. The overall trend, the semantic retrieval of digital libraries from the function could be divided into the service-oriented aggregation and retrieval, the user-oriented aggregation and retrieval,the knowledge reasoning and knowledge innovation -oriented aggregation and retrieval.
