Valerio Arnaboldi, Marco Conti, Massimiliano La Gala, Andrea Passarella, Fabio Pezzoni
2016 Computer Communications  
From the analysis of Twitter ego networks, we have been able to find a direct impact of tie strength and ego network circles on the diffusion of information in the network.  ...  In particular, online ego networks show the same structure found offline, with social contacts arranged in layers with compatible size and composition.  ...  Analysis of information diffusion in twitter ego networks In this section, we investigate how ego network structural properties in OSNs impact on information diffusion.  ...

Information diffusion in distributed OSN: The impact of trusted relationships

Valerio Arnaboldi, Massimiliano La Gala, Andrea Passarella, Marco Conti
2015 Peer-to-Peer Networking and Applications  
Distributed Online Social Networks (DOSN) are a valid alternative to OSN based on peer-to-peer communications.  ...  This means that the effective social network (used for information exchange) may be a subset of the complete social network, and may present different structural patterns, which could limit information  ...  Recent studies on OSN have identified a set of structural properties impacting on the capacity of the network to diffuse information, and the role of different types of users in the diffusion process  ...

Estimation of privacy risk through centrality metrics

J. Alemany, E. del Val, J. Alberola, A. García-Fornes
2018 Future generations computer systems  
Abstract Users are not often aware of privacy risks and disclose information in online social networks.  ...  Otherwise, local and social centrality metrics based on ego-networks provide a suitable approximation to PRS.  ...  However, the message diffusion actions 485 that its neighbors may perform will not have a real risk impact on its privacy.  ...
