Towards an Analysis of Who Creates Clone and Who Reuses it

Code clone analysis is valuable because it can reveal reuse behaviours efficiently from software repositories. Recently, some code reuse analyses using clone genealogies and code clones over multiple projects were conducted. However, most of the conventional analyses do not consider the developers’ individual difference to reuse behaviors. In this paper, we propose a method for code reuse analysis which takes particular note of the differences among individuals. Our analysis method clarifies who reused whose source code across multiple repositories. We believe the result might provide us with constructive perceptions such as characteristics of reused code itself by multiple developers, and developers who implement reusable code.
