开源软件社区知识创造沟通网络演变研究

Evolution of Communication Network for Knowledge Creation of the Open Source Software Community

基于codeplex开源社区中的C#小社区沟通关系数据,利用复杂网络及其零模型方法对开源软件社区知识创造沟通网络演变特性进行研究。分析发现,网络规模前期逐渐增大后期趋于稳定,各阶段无权网络度呈广延指数分布,小世界性比较显著,社团结构显著,存在明显的富人俱乐部现象,没有明显的等级特征,是典型的异配网络;而加权网络权呈幂律分布,没有明显的社团结构特征等。结果表明知识分享、知识流动存在异质性、小世界性,项目协调人之间以及协调人与一般用户交互较多。

The evolution of communication network in the knowledge creation community is studied by join using of the complex network method and null model based on the communication relationships in the codeplex C# small community,which is an open source community. The results show that, the degree distribution of communication network at different stage is a stretched exponential distribution, while the weight of network is a power law distribution. Especially, the characteristic of small world and community structure in these networks are significant, but not in weighted networks. The phenomenon of rich club also exists in these sequence networks. Although the network scale has a gradual increase in stable stage, there is no clear hierarchical characteristic. Hence, it is a typical disassortative network. Therefore, heterogeneity and small word characters appear in this process of knowledge sharing, knowledge flow and the interaction among general users.
