一种基于本体的问题求解学生模型

An Ontology-based Question Solution Student Model

以平面几何问题为对象,通过对主观试题解答进行研究,建立一种基于本体的问题求解学生模型(OSSM).实现了自动问题答案评估学生模型的设计,给出了适用于主观题求解基于本体的知识表示方法、主观题求解过程跟踪方法和答案智能评估方法.用本体方法实现知识表示,可从多方面评估学生对知识点的掌握情况,从而实现对学生学习的智能指导.

With the plane geometry problem as the target, the subjective examination question solution was analyzed to built a kind of the ontology-based question solution student model method （ ontology-based solution student model） so as to realize the assessment of the design of student model, provide the knowledge express method based on ontology and suitable for subjective solution, the follow method in subjective solution process, the assess method in answer intelligence. The ontology method realizes knowledge shows. It can assesses the situation of students mastering knowledge from a lot of respects, so as to realize guiding student studies to a certain extent.
