Systematic Mapping Study of Metrics based Clone Detection Techniques
A code clone is a code fragment that is similar or identical to other code fragments in the source code. Code clones generally occurs in large systems and affects the system maintenance and quality. Removing clones is one way to avoid problems that occur due to the presence of code clones. Clone detection techniques using software metrics provides less complexity in finding the clones. This systematic mapping study focuses on metric based clone detection techniques and various tools used in previous studies. The existing work is classified into different categories and presented in systematic maps. This paper also indicates some problems related to clone detection research.
