Detecting Cross-Project Clones Using Frequent Pattern Mining

Abstract—Code Clones are the similar program structures in a software system. It is one of the main factors in the degradation of the design and structure of software. It complicates the maintenance and evolution of software. There are two types of code clones generally encountered in a software system i.e. Simple code and Complex code clones. In this paper our aim is to generate a system to detect the code clones in an input source text i.e. source code file or the application as a whole is given as an input to the system where it is processed. Second step includes segregating the clones detected into efficient and inefficient clones i.e. the clones in the input file is segregated into the ones which are useful and the other ones which are waste and need to be discarded. The third step is discarding the inefficient ones i.e. here the inefficient clones which are found are discarded from the code and saved into a temporary folder. Keywords—Code clones, detection, efficient and inefficient clones, frequent pattern mining. I
