Abstract:Forks play a central role in modern pull-based OSS development.Although rich empirical results on the participants, challenges, and features of forks have been announced, there is little discussion on quantitatively measuring the population of forks around OSS projects. In this paper, we take a step toward enriching the set of metrics about forks by proposing the fork entropy to measure the diversity of fork populations around OSS projects. We operationalize the proposed fork entropy based on Rao's quadratic e… Show more
