Bursty egocentric network evolution in Skype
Riivo Kikas, Marlon Dumas, Márton Karsai
In this study we analyze the dynamics of the contact list evolution of millions of users of the Skype communication network. We find that egocentric networks evolve heterogeneously…
Spatiotemporal correlations of handset-based service usages
Hang-Hyun Jo, Márton Karsai, Juuso Karikoski +1
We study spatiotemporal correlations and temporal diversities of handset-based service usages by analyzing a dataset that includes detailed information about locations and service…
Correlated dynamics in egocentric communication networks
Márton Karsai, Kimmo Kaski, János Kertész
We investigate the communication sequences of millions of people through two different channels and analyze the fine grained temporal structure of correlated event trains induced b…
Effects of time window size and placement on the structure of aggregated networks
Gautier Krings, Márton Karsai, Sebastian Bernharsson +2
Complex networks are often constructed by aggregating empirical data over time, such that a link represents the existence of interactions between the endpoint nodes and the link we…
Entropy of dynamical social networks
Kun Zhao, Márton Karsai, Ginestra Bianconi
Human dynamical social networks encode information and are highly adaptive. To characterize the information encoded in the fast dynamics of social interactions, here we introduce t…
