Analysis and visualization for clone refactoring

Clone analysis and visualization help in understanding characteristics of clones and indicate potential clones as cost-effective candidates for refactoring. Many studies have analyzed clones and their evolution while a number of techniques have also been proposed for visualizing clones for aiding clone analysis. However, clone analyses and visualizations with respect to inheritance hierarchy and call graphs have remained ignored so far. In this position paper, we argue that such analyses and visualizations are necessary to help in dealing with clones for refactoring.
