A dynamic model of social network formation [PDF]
Proceedings of the National Academy of Sciences, 2000 We consider a dynamic social network model in which agents play repeated games in pairings determined by a stochastically evolving social network. Individual agents begin to interact at random, with the interactions modeled as games. The game payoffs determine which interactions are reinforced, and the network structure emerges as a consequence of

Modeling Groups In Social Networks [PDF]
ECMS 2011 Proceedings edited by: T. Burczynski, J. Kolodziej, A. Byrski, M. Carvalho, 2011 Studies in social network analysis consider the behavior of a group to be equivalent to the "sum" of individual behaviors. However, a group has to be considered as a complex system where emerging phenomena can appear. In this paper, a formalism is proposed to resolve this problematic by modeling groups in social networks using pretopology as a ...

A model to predict communications in dynamic social networks
Social Determinants of Health, 2023 Background: social networks are dynamic due to continuous increases in their members, communications, and links, while these links may be lost. This study was conducted with the aim of investigating the link and communication between social network ...

Modeling Historical Social Networks Databases [PDF]
Proceedings of the Annual Hawaii International Conference on System Sciences, 2019 Historical social networks are analyzed using prosopographical methods. Prosopography is a branch of historical research that focuses on the identification of social networks that appear in historical sources. It aims to represent and to interpret historical data, sourced from texts.

Social recommendation model based on user interaction in complex social networks.
PLoS ONE, 2019 The user interaction in online social networks can not only reveal the social relationships among users in e-commerce systems, but also imply the social preferences of a target user for recommendation services.

Trajectory Linkage and Spreader Centrality for Social Epidemic Networks
IEEE Access, 2020 Constructing social networks for real epidemic cases is very challenging. Many mathematical models have been proposed to model such networks using simulation models, such as susceptible-infected (SI), susceptible-infected-recovered (SIR), and susceptible-

Modeling the Dynamics of Social Networks
, 2008 Modeling human dynamics responsible for the formation and evolution of the so-called social networks - structures comprised of individuals or organizations and indicating connectivities existing in a community - is a topic recently attracting a significant research interest.

A social network model of COVID-19 [PDF]
PLOS ONE, 2020 I construct a dynamic social-network model of the COVID-19 epidemic which embeds the SIR epidemiological model onto a graph of person-to-person interactions. The standard SIR framework assumes uniform mixing of infectious persons in the population. This abstracts from important elements of realism and locality: (i) people are more likely to interact ...
