Software bots act as assistants to help developers in GitHub issues and pull requests (PRs) solution. In this paper, we explore whether software bots affect developer’s sentiment through an empirical study. We find that developers express more neutral sentiment in bot-involved projects and have more positive sentiment in bot-involved issues and PRs. Further, we find developers are less positive in issues and PRs created by bots. To Figure out how developer’s sentiment looks like when mention bots, we use a combination of quantitative and qualitative analyses to explore the different sentiment of developers toward bots and explain the reasons.
