BigCloneEval: A Clone Detection Tool Evaluation Framework with BigCloneBench
Jeffrey Svajlenko, Chanchal Kumar Roy · 2016
Many clone detection tools have been proposed in the literature. However, our knowledge of their performance in real software systems is limited, particularly their recall. We previously introduced our BigCloneBench, a big clone benchmark of over 8 million clones within a large inter-project Java repository containing 25,000 open-source Java systems. In this paper we present BigCloneEval, a framework for evaluating clone detection tools with BigCloneBench. BigCloneEval makes it very easy for clone detection researchers to evaluate and compare clone detection tools. It automates the execution and evaluation of clone detection tools against the reference clones of BigCloneBench, and summarizes recall performance from a variety of perspectives, including per clone type, and per syntactical similarity regions.
