Title: Measuring Affectiveness and Effectiveness in Software Systems,
Abstract: The summary presented in this paper highlights the results obtained in a
four-years project aiming at analyzing the development process of software
artifacts from two points of view: Effectiveness and Affectiveness. The first
attribute is meant to analyze the productivity of the Open Source Communities
by measuring the time required to resolve an issue, while the latter provides a
novel approach for studying the development process by analyzing the
affectiveness ex-pressed by developers in their comments posted during the
issue resolution phase. Affectivenes is obtained by measuring Sentiment,
Politeness and Emotions. All the study presented in this summary are based on
Jira, one of the most used software repositories.
