  Personality traits influence most, if not all, of the human activities, from
those as natural as the way people walk, talk, dress and write to those most
complex as the way they interact with others. Most importantly, personality
influences the way people make decisions including, in the case of developers,
the criteria they consider when selecting a software project they want to
participate. Most of the works that study the influence of social, technical
and human factors in software development projects have been focused on the
impact of communications in software quality. For instance, on identifying
predictors to detect files that may contain bugs before releasing an enhanced
version of a software product. Only a few of these works focus on the analysis
of personality traits of developers with commit permissions (committers) in
Free/Libre and Open-Source Software projects and their relationship with the
software artifacts they interact with. This paper presents an approach, based
on the automatic recognition of personality traits from e-mails sent by
committers in FLOSS projects, to uncover relationships between the social and
technical aspects that occur during the software development process. Our
experimental results suggest the existence of some relationships among
personality traits projected by the committers through their e-mails and the
social (communication) and technical activities they undertake. This work is a
preliminary study aimed at supporting the setting up of efficient work teams in
software development projects based on an appropriate mix of stakeholders
taking into account their personality traits.
