A Visualization Framework for Post-Processing of Association Rule Mining

Association rule mining is one of the most used techniques in data mining. It can be applied in different fields to uncover the hidden relationships in large data sets. Despite that fact, association rule mining algorithms often leave the analyst with the task of analyzing and understanding thousands of rules. Also, this large number of rules cannot be represented effectively in classical visualizations. Thus, the current interest in visualizing data mining is toward applying visual data exploration techniques. These techniques enable the user to interact with graphs. In this paper we introduce a new visualization technique for association mining results based on tree methods, specifically the collapsible tree. To do that, we converted a grouped matrix into a collapsible tree by utilizing R packages. We demonstrate our technique through a market basket analysis case study.
