Abstract
In the data mining fields, we often adopt the selection method that limit great many combinations of item sets to a certain set of rules a priori by the given conditions and thresholds, and some techniques to visualize the selected rules. The oriented graphs, matrix diagrams and Venn diagrams are widely utilized. In this paper, we give a mathematical consideration for representation with Venn diagrams and show some useful conditions for the visualization forms. Next we propose new form of diagram based on the conditions. And we illustrate an implementation using our approach. Finally we discuss the effectiveness of our technique.
