An Exploratory Study of Project Activity Changepoints in Open Source Software Evolution
Tue 18 May 2021 17:03 - 17:06 at MSR Room 1 - Hackathon Chair(s): Jim Herbsleb, Audris Mockus, Alexander Nolte
We used a nonparametric changepoint detection algorithm to measure the smoothness of open source software evolution. Our dataset consisted of 8,919 projects with at least four years of history selected from the World of Code. We found changepoints in project activity time series in 99% of the projects, with most projects having between one and six changepoints. Increases and decreases in project activity occur with roughly equal frequency. While most changes are relatively small, on the order of a few authors or few dozen commits per month, there were long tails of much larger project activity changes.
