：利用语义网技术对信息资源进行语义组织，提供语义检索、语义集成和语义共享等深层次语义服务，已成为知识组织和服务的趋势。国外已有许多研究和服务机构开展信息资源语义组织和语义服务实践，其中以芬兰语义计算研究小组（SeCo）项目实践最具代表性和前沿性。文章从资源类型与标注深度、语义模型、语义数据构建与集成、语义服务这四个方面，对SeCo实践进行分析，研究发现：语义组织的对象从书目向非书目信息资源扩展；语义标注的深度从外部特征向内容语义深入；信息资源的覆盖范围从单一领域向多领域扩展；语义服务从文本向图像可视化发展；语义服务从单一向多样化发展。

Using semantic web technologies to semantically organize information resources and provide deep semantic services such as semantic retrieval, semantic integration and semantic sharing has become a trend of knowledge organization and service. Many research and service organizations in foreign countries have carried out semantic organization and semantic service practice of information resources, among which the projects of the Semantic Computing Research Group (SeCo) in Finland are the most representative and cutting-edge. Thus, this paper analyzes these projects from four aspects: resource type and annotation depth, semantic model, semantic data construction and integration, and semantic service. Then, this paper summarizes their characteristics and enlightens the relevant practice in China: The objects of semantic organization expand from bibliography to non-bibliographic information resources; The depth of semantic annotation goes from external features to content semantics; The coverage of information resources extends from a single domain to multiple domains; Semantic services develop from text to image visualization; Semantic services evolve from single to diverse.
