摘要
针对基于网络的个性化学习的要求,提出把本体技术引入到近年来兴起的一体化虚拟学习环境(IVLEs)中的设想,并给出了一套系统构建方案。利用W3C推荐的RDF对学习资源信息及用户信息进行统一格式的元数据描述,通过对本体实例的描述分析,说明了个性化学习及基于本体的智能检索的实现原理,并对本系统中的本体构建方法做了简述,利用本方案使系统较好地实现了针对不同类型用户的个性化学习及智能检索。
We introduce ontology into an integrated virtual learning environment for the increasing requirement of personalized web learning, and present a system construction scheme. We also employ W3C recommended RDF to describe the unified format metadata of learning resource and user information. We explain the principle of personalized learning and ontology based Intelligent Retrieval by the description and analysis of an ontology instance, and briefly present an ontology building approach of this system. This scheme based system can perform personalized learning and intelligent retrieval for different types of users.
