Description

It is important to know a differrence between two software systems objectively. However, it is hard to compute a quantitative difference from these systems. In this paper, we propose a similarity metric CSR(Corresponding Source-line Ratio) using code clone detection tool CCFinder. We apply CSR to many OSes, and construct an OS genealogy using cluster analysis. As a result, we can classify OSes using CSR. We also find out that there is a high correlation between CSR and development period.
