Mining and analyzing the characteristic of projects collaborative relationship in open source software

Abstract

This paper focus on the relationship between projects that have same participants. A definition of projects collaborative relationship has been presented, and a projects collaborative network model is constructed. By mining and analyzing more than 10000 projects from sourceforge.net, we find that the projects collaborative relationship of software has a great impact on software trustworthiness. The number of project's collaborative project and the proportion of project's participants, who also join in other projects, are mostly important factors of projects collaborative network.
