| 中文摘要: |
| 构建语义化知识服务系统是数字图书馆在语义Web环境下的发展方向.针对目前各种语义Web技术在数字图书馆开发应用的现状和问题,本研究融合国际基于Topic的语义知识组织技术,结合国内的需求,提出了“语义主题模型”,目标为构建可实施的语义化知识系统.文章首先对以“概念化主题、主题关联、语义标签”为内涵的“语义主题化模型”概念进行定义；其次,设计基于此模型的语义化知识系统框架；再次,对相关应用进行了探讨；最后,对未来开发工作进行了规划. |

| Building a semantic knowledge service system is a new direction for digital libraries in the Semantic Web environment. According to the present situation and problems of various Semantic Web technologies in the digital library development and application, this study merges the international semantic knowledge organization technologies based on topic.Combined with domestic demand, it defines a concept of "Semantic Topicized Model", in order to build a semantic knowledge system that can be implemented Firstly, mis paper gives 1he concept of "Semantic Topicized Model", with the intensionof" topicized-description, semantic topic-tagging, topic-associating." Then,it designs of a semantic knowledge system framework based on this model. Finally, it discusses the relevant applications and planning of the future development works. |
