摘要
讨论了建立在模糊系统知识模型之上的范畴与知识的概念,并通过引入粗糙集中上、下近似等基本且重要的概念,在知识模型中给出了标号集关于复合关系的上、下近似等定义,以及给出了知识模型中范畴与知识的近似及其度量方法.对于所给出的有关概念及度量方法通过举例给出了具体说明,为模糊系统知识模型一致性和完备性的讨论奠定基础.
Conceptions of categories and knowledge based on a knowledge model of fuzzy system were discussed,and up and low approximations of label set with complex relation were defined in the knowledge by means of basic and important conceptions in rough sets.Approaches of approximation and measurement for categories and knowledge were given simultaneously.The concept and measurement methods are given by way of example details.The purpose of the study is to provide a basis for discussion of consistency and completeness.
