Formal concept analysis (FCA) originally proposed by Wille [39], is an important theory for data analysis and knowledge discovery. Concept lattice is the core of the mathematical theory of formal concept analysis. To address the requirements of real word applications, concept lattice has been extended to many other forms from the theoretical point of view and possible applications. In this paper,...
Formal concept analysis (FCA) was originally proposed by Wille (1982), which is an important theory for data analysis and knowledge discovery. AFS (axiomatic fuzzy set) algebra was proposed by Liu [X. Liu, The fuzzy theory based on AFS algebras and AFS structure, Journal of Mathematical Analysis and Applications 217 (1998) 459–478; X. Liu, The topology on AFS algebra and AFS structure, Journal of...
