复杂网络中规模异质性对社区识别的影响

Effect of size heterogeneity on community identification in complex networks

Leon Danon, Albert Diaz-Guilera, Alex Arenas

摘要:

识别社区结构是分析和理解复杂网络结构的有力工具。到目前为止,用于评估识别算法的性能的方法使用具有相等大小的社区的ad-hoc网络。我们表明,社区大小的不均匀性可以而且确实会极大地影响算法的性能,并提出了一种考虑这些因素的替代方法。此外,我们提出了一个简单的修改纽曼提出的社区检测算法(物理评论E { \bf 69} 066133),它对待社区的不同大小的平等的基础上,并表明它优于原来的算法,同时保持其速度。

英文摘要:

Identifying community structure can be a potent tool in the analysis and understanding of the structure of complex networks. Up to now, methods for evaluating the performance of identification algorithms use ad-hoc networks with communities of equal size. We show that inhomogeneities in community sizes can and do affect the performance of algorithms considerably, and propose an alternative method which takes these factors into account. Furthermore, we propose a simple modification of the algorithm proposed by Newman for community detection (Phys. Rev. E {\bf 69} 066133) which treats communities of different sizes on an equal footing, and show that it outperforms the original algorithm while retaining its speed.
