| Research Abstract |
In this study, we propose a code clone detection tool based on the similarity of identifiers such as variable names. Code clone is a code fragment that has similar code fragment to it in the source code. To identify similar identifier names, we use synonym identification method proposed in natural language processing. As the evaluation of the tool, we confirm the usefulness by the investigation of the frequencies that simultaneous modification is occurred in detected code clones and detected code clones has the same defect.
