The Visualizing Calculation of Formal Concept That Based on the Attribute Topologies

The calculation of formal concepts is a very important part in the theory of formal concept analysis. This paper proposes a visualization algorithm of formal concept calculation that used the attribute topology of formal context. This algorithm puts the top attributes as the cores to decompose the topology into some sub-topologies,gets all the formal concepts by the visualization full path searching in present sub-topology,combine them to get a full set of concepts of the formal context. Through the analysis of the method,using the full path searching of the sub-topology to get formal concepts not only makes the calculation of formal concept simple and easy to operate,and w ill not result in lost or redundant computing formal concept.
