Comparison and Visualization of Code Clone Detection Results

Abstract

Many techniques for code clone detection have been proposed and implemented as clone detectors in the past. These studies show that a result of code clone detection changes drastically for different tools and/or their detection parameters. Therefore, it is important to apply different clone detectors or different parameters and to identify the different or common parts of the obtained detection results. In this paper, we propose a method for comparison and visualization of detection results based on the correspondence of clone pairs. It enables developers to compare detection results by different tools and/or their detection parameters. Using this method, we will show the comparison results of an OSS using two code clone detectors, CCFinderX and NiCad.
