概念格的粗糙性质研究(英文)
Research on the Rough Properties of Concept Lattice
【摘要】 研究由粗糙集形式的概念格,定义粗糙形式背景、粗糙概念,给出它们的性质,借助蕴涵算子研究上、下近似运算在粗糙形式背景中讨论了粗糙Galois连接。
【Abstract】 The paper studies concept lattice that is formed by rough sets, define rough formal context, rough concept, give their properties, studies the lower (upper) approximate operators by means of implication in rough formal context, and investigate rough Galois connection.
