Abstract:

Traditional rule representation methods cannot show the nature of the relationship between concepts, the lack of understanding of the concept hierarchy, ignoring the problem such as sharing the results of knowledge discovery, and concept lattice as a data structure can succinctly vivid embodiment of generalization and instantiated in the relationship between the concepts, in terms of knowledge visualization and association rules found potential also has a unique advantage. This paper proposes an association rule visualization method with concept lattice as the background, takes concept lattice as the search unit, looks for the association rule path to be displayed in concept lattice, extends the association relation between attributes to the conceptual level, and gives the corresponding visualization strategy and algorithm of multi-pattern rules. Finally, the association rules are analyzed and visualized based on the library data. Experimental results show that the visualization method is effective in knowledge discovery and sharing.
