摘　　要：针对网络课程知识点相对孤立、共享性与重用性差、学习资源查找困难、不能提供个性化服务等问题,提出使用基于本体查询推理的解决方法,设计了检索、查询和推理的功能模块和工作流程,并综合运用了Jena和SPARQL实现了相应的原型系统。通过具体的课程本体进行测试,验证了该解决方法的有效性和可行性。该系统能够将网络课程知识内容有机组织到一起,达到共享、重用的效果,可以提供个性化的学习服务,为进一步开发智能化的网络课程平台提供了条件。In order to tackle the issues such as isolation of knowledge,poor sharing and reusability,difficulty in learning resource founding and personalized service providing in online course,a solution of ontology-based query and reasoning was proposed. The solution designed the function module and working process including retrieval,query and reasoning. A corresponding system was implemented by using Jena and SPARQL. The implementation and experimental results indicated that the method was effective and feasible. It is concluded that this system can provide organic organization,achieve to share and reuse the course knowledge content and personalized learning service,while provide facilities for developing intelligent online course platform.
