The Iterated Local Model for Social Networks [article]

Anthony Bonato, Huda Chuangpishit, Sean English, Bill Kay, Erin Meger
2019 arXiv   pre-print
We propose a new, generative model, referred to as the Iterated Local Model (ILM) for social networks synthesizing both transitive and anti-transitive triads over time.  ...  The previously proposed Iterated Local Transitivity (ILT) and Iterated Local Anti-Transitivity (ILAT) models incorporated transitivity and anti-transitivity, respectively, as evolutionary mechanisms.  ...  The resulting Iterated Local Transitivity (or ILT) model, while elementary to define, simulates many properties of social and other complex networks.  ...

Anthony Bonato and Daniel W. Cranston and Melissa Huggan and Trent Marbach and Raja Mutharasan
2020 arXiv   pre-print
We introduce a new directed graph model for social networks, based on the transitivity of triads.  ...  In the Iterated Local Directed Transitivity (ILDT) model, new nodes are born over discrete time-steps, and inherit the link structure of their parent nodes.  ...  The Iterated Local Transitivity (ILT ) model introduced in [3, 4] and further studied in [2, 17] , simulates social networks and other complex networks.  ...

Structure-based Sybil Detection in Social Networks via Local Rule-based Propagation [article]

Binghui Wang, Jinyuan Jia, Le Zhang, Neil Zhenqiang Gong
2020 arXiv   pre-print
Under our framework, these methods can be viewed as iteratively applying a (different) local rule to every user, which propagates label information among a social graph.  ...  Second, we design a new local rule, which SybilSCAR iteratively applies to every user to detect Sybils.  ...  SybilSCAR iteratively applies our local rule to every user. Our local rule, like RW-based methods and LBP-based methods, leverages the homophily property of social networks.  ...

Disease evolution on networks: the role of contact structure

J. M. Read, M. J. Keeling
2003 Proceedings of the Royal Society of London. Biological Sciences  
In the local networks, high transmission rates are selected for, as there is intense competition for susceptible hosts between disease progeny.  ...  In contrast to mean-field models, the use of contact networks greatly constrains the evolutionary dynamics.  ...  For the local and global networks, the parameters are averaged over 1000 iterations, and again 100 simulations are used.  ...

2017 Journal of Signal Processing  
The spread of viruses, such as flu and SARS, can be modeled using social networks.  ...  In this study, we modeled the spread of a virus in a social network and attempted to suppress the virus by immunizing nodes.  ...  Thus, we evaluated the performance of each immunity placement method not only for the BA model network but also for the WS model network.  ...
