And as such, how developers face their tasks is of major importance. In an environment such as the one that is common in FOSS (free/open source software) projects where professionals (i.e., paid developers) share the development effort with volunteers, the morale of the development and user community is of major importance. In this paper, we present a preliminary analysis using sentiment analysis techniques to a FOSS project. We therefore mine the mailing list of a project and apply these techniques to the most relevant participants. Although the application is at this time limited, we hope that this experience can be of benefit in the future to determine situations that may affect the developers or the project, such as low productivity, developer abandonment, project forking, etc. %B Revista Eletrônica de Sistemas de Informação %V 13 %8 08/2014 %U http://189.16.45.2/ojs/index.php/reinfo/article/view/1677 %N 2 %!

Although this information is publicly available on the Internet, obtaining and analyzing it in a convenient way is not an easy task and many considerations have to be taken into account. In this paper we present the most important data sources that can be found in libre software projects and that are studied by the research community: source code, source code management systems, mailing lists and bug tracking systems. We will give advice for the problems that can be found when retrieving and preparing the data sources for a posterior analysis, as well as provide information about the tools that support these tasks. %B International Journal of Open Source Software and Processes %V 1 %P 24 - 45 %8 31/2009 %N 1 %R 10.4018/jossp.2009010102 %> https://flosshub.org/sites/flosshub.org/files/robles.pdf
