Decentralized Online Social Networks data availability dynamic com- munity P2P

Community structure is one of the most studied features of Online Social Networks (OSNs). Community detection guarantees sev- eral advantages for both centralized and decentralized social networks. Decentralized Online Social Networks (DOSNs) have been proposed to provide more control over private data. One of the main challenge in DOSNs concerns the availability of social data and communities can be exploited to guarantee a more efficient solution about the data availabil- ity problem. The detection of communities and the management of their evolution represents a hard process, especially in highly dynamic social networks, such as DOSNs, where the online/offline status of user changes very frequently. In this paper, we focus our attention on a preliminary analysis of dynamic community detection in DOSNs by studying a real Facebook dataset to evaluate how frequent the communities change over time and which events are more frequent. The results prove that the so- cial graph has a high instability and distributed solutions to manage the dynamism are needed.
