Hierarchical route to the emergence of leader nodes in real-world networks
Joseph D. O'Brien, Kleber A. Oliveira, James P. Gleeson +1
A large number of complex systems, naturally emerging in various domains, are well described by directed networks, resulting in numerous interesting features that are absent from t…
Identification of skill in an online game: The case of Fantasy Premier League
Joseph D. O'Brien, James P. Gleeson, David J. P. O'Sullivan
In all competitions where results are based upon an individual's performance the question of whether the outcome is a consequence of skill or luck arises. We explore this question…
A generalised mean-field approximation for the Deffuant opinion dynamics model on networks
Susan C. Fennell, Kevin Burke, Michael Quayle +1
When the interactions of agents on a network are assumed to follow the Deffuant opinion dynamics model, the outcomes are known to depend on the structure of the underlying network.…
Branching process descriptions of information cascades on Twitter
James P. Gleeson, Tomokatsu Onaga, Peter Fennell +3
A detailed analysis of Twitter-based information cascades is performed, and it is demonstrated that branching process hypotheses are approximately satisfied. Using a branching proc…
Dynamics of cascades on burstiness-controlled temporal networks
Samuel Unicomb, Gerardo Iñiguez, James P. Gleeson +1
Burstiness, the tendency of interaction events to be heterogeneously distributed in time, is critical to information diffusion in physical and social systems. However, an analytica…
Quantifying Uncertainty in a Predictive Model for Popularity Dynamics
Joseph D. O'Brien, Alberto Aleta, Yamir Moreno +1
The Hawkes process has garnered attention in recent years for its suitability to describe the behavior of online information cascades. Here, we present a fully tractable approach t…
