摘要
从知识管理的角度出发,利用知识表达工具概念网络(Connet)为智能教学系统OMT(OlympicMathTutoring)构造知识模型,以“知识树”的形式呈现领域知识的层次和逻辑关系。同时使用覆盖知识树的概率网络建立学生模型,结合习题参数的设计达到解释学生学习行为、为学生提供个性化教学的目的。
How to construct a domain knowledge model for an intelligent tutoring system - OMT (Olympic Math Tutoring) by using connet was discussed, which was considered as a knowledge representation tool, from the point of view of knowledge management. The knowledge model can present the whole framework of the knowledge, not only structural but also logic information through the form of knowledge tree. At the same time, probability network was used to update the knowledge tree by dint of the felicity of exercise parameter design. By this way, the student model can explain the student's action exactly. All these work above can make OMT works well, which means the system can offer an individual tutoring for every student.
