@article{Jo2011EmergenceOB, title={Emergence of Bursts and Communities in Evolving Weighted Networks}, author={Hang-Hyun Jo and Raj Kumar Pan and Kimmo K. Kaski}, journal={PLoS ONE}, year={2011}, volume={6} }
Understanding the patterns of human dynamics and social interaction and the way they lead to the formation of an organized and functional society are important issues especially for techno-social development. Addressing these issues of social networks has recently become possible through large scale data analysis of mobile phone call records, which has revealed the existence of modular or community structure with many links between nodes of the same community and relatively few links between…

Asymptotic theory of time varying networks with burstiness and heterogeneous activation patterns
- Computer Science
- 2017
This work develops a framework that allows for the encoding of three generative mechanisms that seem to play a central role in the social networks' evolution: the individual's propensity to engage in social interactions, its strategy in allocate these interactions among its alters and the burstiness of interactions amongst social actors.
Structural transition in social networks: The role of homophily
- Computer ScienceScientific Reports
- 2019
We introduce a model for the formation of social networks, which takes into account the homophily or the tendency of individuals to associate and bond with similar others, and the mechanisms of…
Dynamics and stability of small social networks

This dissertation presents an unparalleled data collection campaign, collecting highly detailed traces for approximately 1000 people over the course of multiple years, allowing us to probe the underlying social network and understand how individuals interact and form lasting friendships.
Effects of weak ties on epidemic predictability on community networks
- PhysicsChaos
- 2012
The effects of the degree of bridge nodes on the variabilities of both the arrival time and the prevalence of disease are investigated, and it is found that the bridge node with a small degree can enhance the predictability of epidemic spreading.
Modeling the Role of Relationship Fading and Breakup in Social Network Formation
- Computer SciencePloS one

This review presents the emergent field of temporal networks, and discusses methods for analyzing topological and temporal structure and models for elucidating their relation to the behavior of dynamical systems.
Deep Learning Exploration of Agent-Based Social Network Model Parameters
- Computer ScienceFrontiers in Big Data
- 2021
This work focuses on studying a generalization of the weighted social network model, being one of the most fundamental agent-based models for describing the formation of social ties and social networks and believes that this methodology is applicable for a large class of complex network models, thus opening the way for more realistic quantitative agent- based modeling.

Analysis of a large-scale weighted network of one-to-one human communication
- Computer Science

A connected network of 3.9 million nodes from mobile phone call records is constructed, which can be regarded as a proxy for the underlying human communication network at the societal level and a positive correlation between the overlap and weight of a link is reported.

This model includes the opinion-dependent link-rewiring scheme to describe network topology coevolution with a slower time scale than that of the opinion formation and shows the importance of the separation between fast and slow time scales resulting in the network to organize as well-connected small communities of agents with the same opinion.

It is found that, when it comes to information diffusion, weak and strong ties are both simultaneously ineffective, and this coupling significantly slows the diffusion process, resulting in dynamic trapping of information in communities.
