大规模社交网络中基于快照群体行为的无网络数据推理与影响

Inference and Influence of Large-Scale Social Networks Using Snapshot Population Behaviour without Network Data

Antonia Godoy-Lorite, Nick S. Jones

摘要:

投票和接种疫苗等人口行为取决于社交网络。社交网络可以根据行为类型而不同,并且通常是隐藏的。然而,我们经常有大规模的行为数据,尽管只是在一个时间点拍摄的快照。我们提出了一种方法,联合推断大规模的网络结构和网络模型的人类行为只使用快照人口行为数据。这利用了简单的几个参数,几何社会人口网络模型和基于自旋的行为模型。我们举例说明,欧盟公投和两个伦敦市长选举,该模型如何提供预测和解释我们的同性恋倾向。除了从大规模行为数据集中提取特定于行为的网络结构之外,我们的方法还产生了一个将不平等和社会偏好与行为结果联系起来的粗略计算。我们给出了潜在的网络敏感政策的例子:收入不平等,社会温度和同性恋偏好的变化如何在最近的选举中减少两极分化。

英文摘要:

Population behaviours, such as voting and vaccination, depend on social networks. Social networks can differ depending on behaviour type and are typically hidden. However, we do often have large-scale behavioural data, albeit only snapshots taken at one timepoint. We present a method that jointly infers large-scale network structure and a networked model of human behaviour using only snapshot population behavioural data. This exploits the simplicity of a few parameter, geometric socio-demographic network model and a spin based model of behaviour. We illustrate, for the EU Referendum and two London Mayoral elections, how the model offers both prediction and the interpretation of our homophilic inclinations. Beyond offering the extraction of behaviour specific network structure from large-scale behavioural datasets, our approach yields a crude calculus linking inequalities and social preferences to behavioural outcomes. We give examples of potential network sensitive policies: how changes to income inequality, a social temperature and homophilic preferences might have reduced polarisation in a recent election.
