摘要
提出了广义 Fuzzy 集合与 Fuzzy 属性文法的概念,并给出了 Fuzzy 属性文法的分解定理与表现定理,从两个不同的角度阐明了 Fuzzy 属性文法与普通文法以及它们的代数结构之间的关系。
This paper gives the concept of extended fuzzy sets and fuzzy attributedgrammars and decomposition theorems and representation theorems for fuzzy attributedgrammars.Each theorem discloses,from two distinct points of views,the relationshipbetween a fuzzy attributed grammar and a group of non-fuzzy grammars,and the re-lationship among their algebraic structures.
