【摘要】 本文主要研究基于超媒体的智能教学系统的设计和开发。首先，在分析我国教学模式的基础上，以《线性代数》为智能教学系统的内容载体，建立了教学模型；其次，利用超媒体的特殊结构，使用语义网络方法进行了知识表示研究；第三，在推理机制上，采取两级推理相结合的方法进行推理，即用基于语义网络的推理确定教学内容，用基于产生式规则的推理确定教学策略，并给出了详细的推理算法；第四，采用基于信息论的示例学习，实现了机器学习算法并建立了机器学习决策树。本智能教学系统具有界面友好，操作简单，通用性强等特点。可为学生提供一个优秀的学习环境，为教师提供一个制作智能课件的良好的模板，具有很大的实用价值和推广意义。更多还原

【Abstract】 The main study in this paper is how to design and develop an intelligent tutoring system based on hypermedia (HITS). First of all, after analyzing Chinese teaching mode, and taking the linear algebra as content, the teaching model is composed. Secondly, making use of the special configuration of hypermedia, the semantic network is used to research knowledge representation. Thirdly, on reasoning mechanism, combining means of two classes reasoning is taken. Namely the teaching content is made certain by the reasoning based on semantic network, and the teaching strategy is established by the reasoning based on production rule. The paper introduces the detailed reasoning algorithm to both. Fourthly. making use of Learning from examples based on information theory, machine learning algorithm and machine learning decision tree is realized. We have designed and developed HITS that has had the virtues of friendly interface, simple operation, and good commonality. HITS can provide a good learning entironment for students and a good formwork of making intelligent courseware for teacher. It has strong utility value and significance of generalization.更多还原
