| 摘 要： | 知识门户为用户提供了万维网上基于特定学科领域信息的视窗，方便用户查找相关的、特定学科的信息。智能存取系统（Intelligent Access）的构建与知识门户的信息供应需要进行大量的人工编辑和维护工作。为了减轻这些人工劳动，在构建与维护知识门户的综合方法中，可以利用Ontology作为概念的中枢提供和访问信息，并将信息结构化。

| Abstract: | Knowledge portals provide views onto domain-specific information on the World Wide Web, thus facilitating their users to find relevant, domain-specific information. The construction of intelligent access and the provisioning of information to knowledge portals, however, it requires extensive manual editing and maintenance by the knowledge portal providers. In order to diminish these efforts using Ontology as a conceptual backbone for providing, accessing and structuring information in a comprehensive approach for building and maintaining knowledge portals. There are one research and one commercial case study that show how our approach is used in practice. |
