| 摘 要： | 研究者发现许多真实网络中存在分形特征,并广泛认为网络的异配性导致了分形性。因此,具有同配性的社交网络的分形特征很少被研究。针对开源合作平台中存在许多大型项目的开发者之间未必有实际的合作关系的现象,引入了边的权重来移除弱连接的边。通过重整化群分析,发现GitHub网络在移除弱连接的边之后,其网络结构从小世界变化为分形网络。此外,对网络的Pearson相关系数和邻居相关度进行分析后,发现网络具有很强的同配性,验证了之前对分形起源的理论分析。

| Abstract: | Researchers have found that many real-world networks have fractal properties.It is widely believed that the fractal property origins from disassortative mixing.Thus,the fractal property of social networks,which are mostly assortative mixing, is rarely investigated.As in the open-source collaboration platform,there are many large projects,where many developers do not have real collaboration activities.In the paper,we introduced the power of links to remove the weak links in the network.Based on the renormalization group analysis,we found the network transfers from small-world to fractal network when we removed the weak links.Furthermore,by analyzing the Pearson correlation coefficient and neighbor connectivit y, we found the fractal networks formed by strong links are assortative mixing.It enhances our former conclusion on the origin of fractality. |
