基于扩展语义网的知识资源组织技术研究

Knowledge Resources Organization Technology Research Based on Expended Semantic Web

采用知识点的方式组织知识资源,有利于知识的获取、分享、分配和存取。但是传统的树型结构对知识的整体关系描述能力不足,不利于分布式环境下对知识资源的查找和定位。语义网是一种可以详细描述本体间复杂关系并具有天然分布式特性的技术。然而一般的语义网本身不是按照知识点的方式进行组建。本文对语义网进行扩展,使其适用于描述基于知识点组织的知识资源。通过应用案例,按照知识点进行扩展的语义网可以有效地描述知识资源间的相互关系,便于知识的理解和利用,并且对知识的查找和定位也变得更加方便。

Knowledge points are used to organize knowledge resources, which is convenient to knowledge acquisition, sharing, distribution and visit. But the traditional tree structure is lack of ability to knowledge overall relationship＇s description, and it is not convenient to the search for knowledge resources and positioning in distributed environments. Semantic Web is a technology which can describe complex relationships between ontology in details and with the natural characteristics of the distributed. However, the general semantic Web is not constructed in accordance with knowledge points. The semantic Web has been expanded in the paper, so that it can be applied to describe knowledge points-based knowledge resources. Case studies demonstrated that the expended semantic Web can effectively describe the interrela- tionships between knowledge resources, it is easy to understand and use the knowledge, and location and positioning of knowledge have become more convenient.
