## 5 Conclusions
In light of this study, we are planning another study involving a survey of junior and senior developers whom we can contact to understand the ground truth of our metrics' success (especially metrics related to commenting activities). In addition, we plan to apply these metrics to solve various problems. For instance, many developers, in addition to owners and collaborators, can make contributions to projects thanks to the open-source nature of GitHub. On some projects, external developers even contribute more than the core team. These metrics can reveal developers' contribution rankings on a particular project.
