Abstract

At present, there are various kinds of code clone detection techniques. PDG-based detection is suitable to detect non-contiguous code clones meanwhile other detection techniques are not suited to detect them. However, there is a tendency that it cannot detect contiguous code clones unlike string-based or token-based technique.This paper proposes two techniques to enhance the PDG-based detection for practical usage.The software tool, Scorpio has been developed based on the techniques.
