- Abstract:
-
As an effective tool for knowledge discovery and data processing, concept lattices have been widely applied in many fields, and in these applications, it is important to efficiently construct concept lattice. The formal context of each concept lattice corresponds to a bipartite graph. In this paper, the maximum complete subgraph of a bipartite graph is used to generate a concept lattice, and then where an iterative algorithm with depth priority is proposed based on a bipartite graph. The process is as follows:first, a formal context is reduced; then, the direct subconcepts of the top concept are obtained using maximal complete-subgraph of bipartite graph; finally, through the derivation of the induced subgraph of bipartite graph to reduce the formal context, and find direct subconcepts and all subconcepts of every concept, then the concept lattice was established.
