同质性是社会网络分析中的一个概念,它指出在一个网络中,如果两个人有共同的特征,那么链接的可能性更大。我们研究观察者是否可以通过查看网络的节点链接图来评估同质性的问题。我们设计了一个实验,调查三种不同的布局算法,并要求用户估计显示的网络中的同质性程度。其中一种布局算法是经典的力导向布局算法,另外两种布局算法是基于共同特征来提高节点区分度。我们研究了三种布局算法如何帮助获得公平的估计,以及是否有过度或低估同质性程度的倾向。我们实验中的刺激使用不同的网络大小和不同比例的集群大小。
Homophily is a concept in social network analysis that states that in a network a link is more probable, if the two individuals have a common characteristic. We study the question if an observer can assess homophily by looking at the node-link diagram of the network. We design an experiment that investigates three different layout algorithms and asks the users to estimate the degree of homophily in the displayed network. One of the layout algorithms is a classical force-directed method, the other two are designed to improve node distinction based on the common characteristic. We study how each of the three layout algorithms helps to get a fair estimate, and whether there is a tendency to over or underestimate the degree of homophily. The stimuli in our experiments use different network sizes and different proportions of the cluster sizes.
