本体E-Learning系统中的情境感知技术研究

Study on context-aware technologies for ontology E-Learning system model

引入情境感知的相关概念和技术,结合本体E-Learning环境的特点,根据感知到的学习者学习过程中的学习情境信息建模.该模型能够主动感知用户情境的变化并进行信息交互,通过分析学习者的个性化需求主动提供学习资源服务.最后,应用实例验证了本文构建的系统能够实现学习资源服务的自适应服务.

The models were constructed based on the perceived learners＇ learning situations information in their learning process, after introducing the brief ontology and context - aware applications. The initiative was taken to perceive changes in the user context and information exchange and individual needs of the learners, so to provide learning resources service. Finally, the applied example proves that the system can achieve the adaptive learning resources services.
