Using Source Code Density to Improve the Accuracy of Automatic Commit Classification into Maintenance Activities
[article]
2020
arXiv
pre-print
Preserved Fulltext
We introduce source code density, a measure of the net size of a commit, and show how it improves the accuracy of automatic commit classification compared to previous size-based classifications. ...
We also investigate how preceding generations of commits affect the class of a commit, and whether taking the code density of previous commits into account can improve the accuracy further. ...
Acknowledgments We would like to thank the anonymous reviewers for their invaluable comments, which helped us to further improve this work. ...
