Software Engineers' Questions and Answers on Stack Exchange

Abstract: There exists a large number of research works analyzing questions and answers on the popular Stack Overflow website. However, other sub-sites of the Stack Exchange platform are studied rarely. In this paper, we analyze the questions and answers on the Software Engineering Stack Exchange site that encompasses a broader set of areas, such as testing or software processes. Topics and quantities of the questions, historical trends, and the authors' sentiment were analyzed using downloaded datasets. We found that the asked questions are most frequently related to database systems, quality assurance, and agile software development. The most attractive topics were career and teamwork problems, and the least attractive ones were network programming and software modeling. Historically, the topic of domain-driven design recorded the highest rise, and jobs and career the most significant fall. The number of new questions dropped, while the portion of unanswered ones increased.
