网络中的社会分层:来自合著网络的见解

Social Stratification in Networks: Insights from Co-Authorship Networks

Zeinab S. Jalali, Josh Introne, Sucheta Soundarajan

摘要:

据观察,现实世界的社交网络往往表现出沿经济或其他路线的分层,其后果是阶级流动和获得机会。随着人类交互数据的增加和在线社交网络的广泛使用,社交网络的结构(表示个体之间的联系)可以用于测量分层。然而,尽管社会科学对分层进行了广泛的研究,但没有一个单一的、普遍适用的指标来衡量网络中的分层水平。在这项工作中,我们首先提出了新的分层协同性(StA)度量,它衡量网络分层到不同层次的程度。然后,我们使用\texttt{StA}度量来对五个合著网络的分层进行深入分析。我们研究了这些网络的演变超过50年,并表明,这些领域表现出越来越多的分层随着时间的推移,相应地,研究人员的职业生涯的轨迹越来越多地与她进入网络的入口点。

英文摘要:

It has been observed that real-world social networks often exhibit stratification along economic or other lines, with consequences for class mobility and access to opportunities. With the rise in human interaction data and extensive use of online social networks, the structure of social networks (representing connections between individuals) can be used for measuring stratification. However, although stratification has been studied extensively in the social sciences, there is no single, generally applicable metric for measuring the level of stratification in a network. In this work, we first propose the novel Stratification Assortativity (StA) metric, which measures the extent to which a network is stratified into different tiers. Then, we use the \texttt{StA} metric to perform an in-depth analysis of the stratification of five co-authorship networks. We examine the evolution of these networks over 50 years and show that these fields demonstrate an increasing level of stratification over time, and, correspondingly, the trajectory of a researcher's career is increasingly correlated with her entry point into the network.
