| Outline of Final Research Achievements |
In this research, we analyze the relationship between the transitions of the developers' emotional polarities of commit comments and the characteristics of the projects, by applying sentiment analysis to the commit comments stored in source code repositories.
We apply this experiment to four open source software projects. As a result, we found that there are cases where there is a significant difference in their emotional polarities among those two groups of the four projects which divided based on the characteristics of the projects and mainly used programming language. We also found and analyzed that there are comments that inconvenience when applying sentiment analysis to commit comments.
