摘　　要：针对当前e-learning系统中存在着资源利用效率低和学习内容单一、个性化不足等问题,设计一个基于本体的web挖掘的个性化e-learning系统,通过应用web挖掘和本体技术,使得该系统能根据学习者的知识结构、学习目标、学习风格、偏好等特征信息提供适应学习者的教学方法和学习资源,营造个性化的网络学习环境。实验表明本体技术能明显改善挖掘效果,提高学习资源库的管理效率,有效促进学生的网络学习,满足学生个性化学习的需求,为系统的决策分析提供了智能的辅助手段。Aiming at the low efficiency of the uses of instructional materials and personalized is simplified in existing the current e-learning system,this paper presents a novel system of personalized e-learning of ontology-based web mining,by the application of web mining and ontology technologies making the system according to the learner＇s knowledge structure,learning objectives,learning styles,preferences and other information providers to adapt to learner characteristics of teaching methods and learning resources,and create a personalized Web learning environment. Experimental results show the system can improve the effectiveness of Web mining and instructional materials＇ manegement and the quality of international learning and meet the requirements of the students learning needs and offer intelligent auxiliary methods for decision analysis.
