Formal concept analysis is a field of applied mathematics based on mathematical analysis of concept and conceptual hierarchy,AFS algebra was first proposed and studied by Xiaodong Liu 1998 ( Journal of Mathematical Analysis and Applications, vol. 217, Fuzzy Sets and Systems, vol. 95 )[1,2]. In this paper, we explore the relationships between concept lattices, the AFS algebra, we analyze concept from the point of AFS algebra , We pave a way to explore concept lattice with AFS theory.
