Discovering Homophily in Online Social Networks
2018
During the last ten years, Online Social Networks (OSNs) have increased their popularity by becoming part of the real life of users.

The analysis of the users’ similarity in OSNs is attracting the attention of researchers because of its implications on privacy and social marketing. In particular, the homophily between users could be used to reveal important characteristics that users would like to keep hidden, hence …
Predicting the availability of users' devices in Decentralized Online Social Networks
2018

As a result, the availability of data in these systems is strongly affected (or reflected) by the temporal behavio…

Understanding the sense of community and continuance intention in virtual communities: The role of commitment and type of community
2019
Virtual communities (VCs) have become essential in current organizations and society, and so their sustainability is a topic of interest for researchers and practitioners. We focus on the sense of virtual community (SoVC) and commitment as relevant antecedents in achieving the success and maintenance of different types of VCs (communities of interest, virtual learning communities, and virtual communities of practice). Specifically, this study examines a moderated mediation model in which the type of virtual community moderates the indirect effect of a SoVC on the intention to continue through the perceived commitment of the users of the VC. The sample consists of 299 members of Virtual comm…
