How to Quantify Polarization in Models of Opinion Dynamics
Christopher Musco, Indu Ramesh, Johan Ugander +1
It is widely believed that society is becoming increasingly polarized around important issues, a dynamic that does not align with common mathematical models of opinion formation in…
Prioritized Restreaming Algorithms for Balanced Graph Partitioning
Amel Awadelkarim, Johan Ugander
Balanced graph partitioning is a critical step for many large-scale distributed computations with relational data. As graph datasets have grown in size and density, a range of high…
Scaling Choice Models of Relational Social Data
Jan Overgoor, George Pakapol Supaniratisai, Johan Ugander
Many prediction problems on social networks, from recommendations to anomaly detection, can be approached by modeling network data as a sequence of relational events and then lever…
An Experimental Study of Structural Diversity in Social Networks
Jessica Su, Krishna Kamath, Aneesh Sharma +2
Several recent studies of online social networking platforms have found that adoption rates and engagement levels are positively correlated with structural diversity, the degree of…
Measuring Directed Triadic Closure with Closure Coefficients
Hao Yin, Austin R. Benson, Johan Ugander
Recent work studying triadic closure in undirected graphs has drawn attention to the distinction between measures that focus on the "center" node of a wedge (i.e., length-2 path) v…
Choosing to Grow a Graph: Modeling Network Formation as Discrete Choice
Jan Overgoor, Austin R. Benson, Johan Ugander
We provide a framework for modeling social network formation through conditional multinomial logit models from discrete choice and random utility theory, in which each new edge is…
