文中首先引入知识网相关的概念和定义,然后通过分析知识网的完整性特性,引入合理性检验理论,根据知识网完备性理论,提出了基于知识网约束的合理性检验方法。然后针对知识网中存在的父子功能约束、功能信息流约束特点,采用自动选择知识点的方法,实现添加知识点到已选知识点中,构成完整的知识网。最后,再通过实例,显示基于知识网约束的知识点选择的合理性检验过程,并根据所选知识点,生成动态知识网模型,表明基于知识网约束的合理性检验方法是可行的。
Introduce the related conception and definition about knowledge mesh firstly, and then through the characteristic analysis of the integrity of knowledge mesh, a rationality checking theory is introduced, and according to the theory of the integrity of knowledge mesh, a method of rationality checking based on the restrictions of knowledge mesh is proposed. Considering the characteristics of the restriction between father and son functions, and the restriction between function and information flow, the method of selecting knowledge points automatically is used in this paper, realizing that knowledge points are added to the selected knowledge points to construct an entire knowledge mesh. Finally, the example shows the process of rationality checking of knowledge point selection based on the restrictions of knowledge mesh, and generates a model of dynamic knowledge mesh using the selected knowledge points. And it shows that the method of rationality checking based on the restrictions of knowledge mesh is feasible.
