Communities consist of groups of experienced users or developers who contribute to the improvement of the operating system, the contribution of communities can be seen in a practical way in the package repositories. The study of the interactions that the developers of these packages establish based on common interests, helps to identify their communities, promotes collaboration between development teams, and helps to determine the critical developments, leaders, experts or most influential actors. The aim of this research is to develop a method for determining communities of developers and more influential actors in free software repositories. A study was carried out on concepts associated with graph theory, collaborative network analysis, algorithms for community detection and centrality measurements. In addition, the implementation process of the presented method was described and different tests were carried out in order to verify the quality of the solution. The final result was a method that facilitated the search for packages in free software repositories and the extraction of change control files from each of these. The method implemented facilitated the extraction of the names of packages and their developers. Gephi Toolkit allowed visualize the detected collaborative networks and distinguish the most influential communities and actors, allowing to strength the collaboration between development teams.

Keywords : collaborative network analysis; communities; community detection; centrality measures; free software repositories.
