多层开发者-项目二部网络的协作相似性分析

Collaborative similarity analysis of multilayer developer-project bipartite network

Deng-Cheng Yan, Bing-Hong Wang

摘要:

为了从整体上理解GitHub上开发人员和项目之间的多重关系,我们将它们建模为多层二分网络,并分析度分布,最近邻居的度分布及其与度的相关性,以及协作相似性分布及其与度的相关性。结果表明,所有的度分布都具有幂律形式,特别是观看层项目的度分布具有双幂律形式。最近邻度与开发者度和项目度之间的负相关性在两个层中都被观察到,表现出一种离散的混合模式。开发者与项目的合作相似度在观看层与合作程度呈负相关,在分叉层与合作程度呈正相关,在分叉层与合作程度无明显相关性。

英文摘要:

To understand the multiple relations between developers and projects on GitHub as a whole, we model them as a multilayer bipartite network and analyze the degree distributions, the nearest neighbors' degree distributions and their correlations with degree, and the collaborative similarity distributions and their correlations with degree. Our results show that all degree distributions have a power-law form, especially, the degree distribution of projects in watching layer has double power-law form. Negative correlations between nearest neighbors' degree and degree for both developers and projects are observed in both layers, exhibiting a disassortative mixing pattern. The collaborative similarity of both developers and projects negatively correlates with degree in watching layer, while a positive correlations is observed for developers in forking layer and no obvious correlation is observed for projects in forking layer.
