摘要	While complexity is an essential problem inherent in software system and its development, OSS (Open-Source Software) is not an exception and is not immune to this problem as well. The fast growth of OSS movement has impressed us with reduced cost but high quality software. To learn some lessons from successful OSS in handling the complexity, social network analysis is prevalent in analyzing both human-aspect and source-code-aspect interaction of OSS. This paper conducted an empirical study of an OSS project-ArgoUML. Unlike most previous studies regarding OSS email archives as a whole social network, our focus is on the quantitative analysis of a series of social networks produced in the process of OSS version evolution and module development. Through the empirical study, we have found that all the social network measures employed in this study are comparable to identify core developers of ArgoUML project. The frequency of co-occurrence of developers within the same topic is not a decisive factor to identify core developers. Developers within the same module communicate closely and frequently with each other. The more modules a developer developed, the more communication he (or she) will have with other developers. Although participants of developers' mailing lists are fluctuating in a large magnitude, the committers of the source code are kept stable in each version evolution. Moreover, the variation of committers of source code in version evolutions is almost unpredictable based on the variation of participants in developers' mailing lists. © 2011 ACM.; While complexity is an essential problem inherent in software system and its development, OSS (Open-Source Software) is not an exception and is not immune to this problem as well.
