Using source code density to improve the accuracy of automatic commit classification into maintenance activities

null null Source code is changed for a reason, e.g., to adapt, correct, or adapt it. This reason can provide valuable insight into the development process but is rarely explicitly documented when the change is committed to a source code repository. Automatic commit classification uses features extracted from commits to estimate this reason. null We introduce source code density, a measure of the net size of a commit, and show how it improves the...
