Clone tracking is a fundamental technique of research on code clones. There exists some techniques to track clones across version histories, but they still remain some issues. This paper proposes a new technique, which is an enhancement of the existing CRD-based clone tracking. We have developed a tool as an implementation of the proposed method, and conducted an experiment to confirm the improvement of accuracy of clone tracking compared to the existing technique. The experimental results showed a lot of instances newly tracked by the proposed method, and approximately 91% of newly detected tracking are correct.
