摘要:

研究OSS协作网络中的社区形成问题。虽然目前大多数工作都在研究小规模OSS项目的出现,但我们的方法借鉴了180万GitHub用户及其存储库贡献的大规模历史数据集。开放源码软件协作的特点是,小规模的用户群体密切合作,从而在基础网络结构中形成由短周期界定的社区。为了理解这种现象的影响,我们应用了一个预处理步骤,该步骤通过使用Renewal-Nonbacktracking Random Walks(RNBRW)和成对协作的强度来解释循环网络结构,然后再实施Louvain方法来识别网络中的社区。装备鲁汶RNBRW和贡献强度提供了一个更自信的方法来检测小规模的团队,并揭示了社区发现的重要差异,如用户倾向于优先连接到更成熟的协作社区。使用这种方法,我们还确定了影响社区形成的关键因素,包括用户位置和主要程序设计语言的影响,这是使用贡献活动的比较方法确定的。总的来说,本文提供了几个有前途的方法论的见解,开源软件专家和网络学者有兴趣研究团队的形成。

英文摘要:

This paper studies community formation in OSS collaboration networks. While most current work examines the emergence of small-scale OSS projects, our approach draws on a large-scale historical dataset of 1.8 million GitHub users and their repository contributions. OSS collaborations are characterized by small groups of users that work closely together, leading to the presence of communities defined by short cycles in the underlying network structure. To understand the impact of this phenomenon, we apply a pre-processing step that accounts for the cyclic network structure by using Renewal-Nonbacktracking Random Walks (RNBRW) and the strength of pairwise collaborations before implementing the Louvain method to identify communities within the network. Equipping Louvain with RNBRW and the contribution strength provides a more assertive approach for detecting small-scale teams and reveals nontrivial differences in community detection such as users tendencies toward preferential attachment to more established collaboration communities. Using this method, we also identify key factors that affect community formation, including the effect of users location and primary programming language, which was determined using a comparative method of contribution activities. Overall, this paper offers several promising methodological insights for both open-source software experts and network scholars interested in studying team formation.
