Construction Algorithm of Concept Lattice Based on Attribute Covered

Formal concept analysis is a powerful tool for data analysis,which has been widely used in many areas.Concept lattice is the main data structure for formal concept analysis theory,so how to build concept lattice is the premise for many applications.The paper analyzes the algorithm building concept lattice in the way of top-down structure,in which sub-concepts conver it's super-concepts' attribute sets.The paper presents a new concept lattice construction algorithm,it's based primarily on the No.N layer concepts' object sets must be the maximum coverage of their properties,which simplifies the process of constructing the concept lattice.
