Discrete Temporal Models of Social Networks
We propose a family of statistical models for social network evolution over time, which represents an extension of Exponential Random Graph Models (ERGMs). Many of the methods for ERGMs are readily adapted for these models, including MCMC maximum likelihood estimation algorithms. We discuss models of this type and give examples, as well as a demonstration of their use for hypothesis testing and...
متن کاملSocial Discrete Choice Models
Human decision making underlies data generating process in multiple application areas, and models explaining and predicting choices made by individuals are in high demand. Discrete choice models are widely studied in economics and computational social sciences. As digital social networking facilitates information flow and spread of influence between individuals, new advances in modeling are nee...
متن کاملModels, Entropy and Information of Temporal Social Networks
Temporal social networks are characterized by heterogeneous duration of contacts, which can either follow a power-law distribution, such as in face-to-face interactions, or a Weibull distribution, such as in mobile-phone communication. Here we model the dynamics of face-to-face interaction and mobile phone communication by a reinforcement dynamics, which explains the data observed in these diff...
متن کاملAnalysis of Temporal Evolution of Social Networks
The article presents an analysis of dynamic social network where words, nodes and edges appear and disappear through time. We study a popular virtual social network in the internet, known as Paltalk. We analyze the exact and approximated cyclic entropy variation with time with the purpose to establish the robustness of the network. In addition, we study the effect of weighed links on the analys...
متن کاملModels of Online Social Networks
We present a deterministic model for on-line social networks (OSNs) based on transitivity and local knowledge in social interactions. In the Iterated Local Transitivity (ILT) model, at each time-step and for every existing node x, a new node appears which joins to the closed neighbour set of x. The ILT model provably satisfies a number of both local and global properties that were observed in O...
