摘要
概念格是研究和处理概念内涵与外延确定性关系的数学方法 ,已成为一种有效的数据分析方法。本文进一步探讨概念内涵与外延的不确定关系的模糊映射 ,给出相应的隶属函数的一些基本数学性质 ,证明全体模糊概念构成一个完全格。
Concept lattice is an approach to deal with the certainly relation of intension and extension of concept, a powerful mathematical way for data analysis. In this article the uncertainly relations of fuzzy mapping for the intension and extension of concept are discussed based on concept lattice, some basic mathematical laws of corresponding membership function are given. It is proved that all of fuzzy concepts constitute a complete lattice.
