基于LBS的情境感知微学习系统设计与应用

Design and Application of Context-Aware Micro-Learning System Based on LBS

微学习为满足知识经济时代人们对终身学习的需求提供了一种可能。在这种走进田野的学习活动中,基于LBS实时情境感知的知识服务是增强微学习效果的重要方法。文章在分析微学习活动特征基础上,提出了描述微学习中学习情境的通用本体模型,并以情境交际英语学习系统开发为例,构建了基于WordNet扩展的应用知识本体,实现了支持位置情境感知和语义查询的微学习系统原型。测试结果表明,该系统能较好地适用于对实时性要求较高的交际英语微学习场合。

Micro learning provides a possible way to meet the demand of lifelong learning in the knowledge economy. Under the perspective of micro-learning as a filed learning model, knowledge service based on LBS real time context awareness is an important way to improve learning effect. This paper proposed a general ontology model to describe micro learning situation. Take situational communicative English learning system as an example, a domain knowledge ontology extended from WordNet was constructed, and a prototype system of micro-learning system supporting location-awareness and semantic query was implemented. The test result showed this system can well meet the micro learning situations of communicative English with high real-time demand.
