符号网络中部分平衡的度量

Measuring Partial Balance in Signed Networks

Samin Aref, Mark C. Wilson

摘要:

敌人的敌人一定是朋友吗?如果不是,这在多大程度上倾向于成立?这些问题是根据签名(社会)网络制定的,并在1960年左右获得了网络“平衡”的必要和充分条件。从那时起,签名网络随着时间的推移趋于变得更加平衡的想法已被广泛应用于多个应用领域。然而,由于缺乏部分平衡的标准衡量标准,对这一假设的研究变得复杂,因为在实践中几乎从未实现过完全平衡。我们形式化的部分平衡的措施的概念,讨论各种措施,比较合成数据集上的措施,并调查其公理性质。合成数据涉及Erdens-Rényi和特殊结构的随机图。我们表明,一些措施的行为比别人更好的公理和能力,区分图。我们还使用了来自社会学和生物学文献的知名数据集,例如Read的新几内亚部落,与两种生物体相关的基因调控网络,以及涉及参议院法案共同赞助的网络。我们的研究结果表明,在基于周期,基于特征值和基于挫折的措施下,观察到实质上不同水平的部分平衡。我们提出了一些建议,供今后工作中使用的措施。

英文摘要:

Is the enemy of an enemy necessarily a friend? If not, to what extent does this tend to hold? Such questions were formulated in terms of signed (social) networks and necessary and sufficient conditions for a network to be "balanced" were obtained around 1960. Since then the idea that signed networks tend over time to become more balanced has been widely used in several application areas. However, investigation of this hypothesis has been complicated by the lack of a standard measure of partial balance, since complete balance is almost never achieved in practice. We formalize the concept of a measure of partial balance, discuss various measures, compare the measures on synthetic datasets, and investigate their axiomatic properties. The synthetic data involves Erdős-Rényi and specially structured random graphs. We show that some measures behave better than others in terms of axioms and ability to differentiate between graphs. We also use well-known datasets from the sociology and biology literature, such as Read's New Guinean tribes, gene regulatory networks related to two organisms, and a network involving senate bill co-sponsorship. Our results show that substantially different levels of partial balance is observed under cycle-based, eigenvalue-based, and frustration-based measures. We make some recommendations for measures to be used in future work.
