Evolving and Hot Topics on Code Clone Detection Techniques

Abstract

A code clone is typically created by a developer reusing a code fragment in a copy-and-paste manner. Such copied code fragments usually exist in source code of almost every software products. The code clones are known as potential troubles in maintenance, while we can learn kinds of knowledge from the existence of such code fragments. This paper explains about topics about code clone, especially detection methods of code clones and various applications of the detection methods.
