基于复杂网络的开源软件社区的结构异质性

Structural Heterogeneity of Open-Source Software Communities Based on Complex Networks

我们生活的世界,尤其是在互联网与大数据时代,不仅包含以同质性为特点的高斯世界,也包含以异质性为特点的帕累托世界.文中针对复杂网络学界对异质性测度的不同看法,首先探讨了异质性的含义、分类以及基本测量方法;然后将开源软件的大众生产社区看成一种新型的组织,以Codeplex C#社区为例,用上述测量方法去揭示这种组织结构的异质性;最后归纳出用复杂网络模型分析开源社区结构异质性的具体步骤,并给出组织异质性的物理学背景与研究意义.

People have gradually realized that the world we live in,especially in the current times of the Internet and big data,includes not only a homogeneous Gauss world but also a heterogeneous Pareto world.Aiming at the debates about the measurement of heterogeneity in the complex network circle,this paper first deals with the mea-ning,classification and basic measurement method of heterogeneity,and then regards the peer production community of open-source software in the Internet as a new-type organization and hence reveal the heterogeneity of its organiza-tion structure through the heterogeneity meaning and relevant parameters of complex network,with a Codeplex C#community being taken as the example.Finally,the practical steps for analyzing the structural heterogeneity via complex network models are summarized,and the physical background and research significance of structural hete-rogeneity of organization are discussed.
