Method-based Code Clone Detection for a Large Number of Software Systems

It is predicted that there are many code clones across software systems. Detecting such code clones is useful from the viewpoint that we can discover source code licensing violations or merge common functions into libraries. However, existing research cannot detect code clones which are a part of a source file. In this research, we developed a tool that quickly detects method-based code clones and experimented on a huge set of software systems.
