The diffusion of Online Social Networks (OSNs) has had a profound effect on the way we interact and a deep impact on society and business. OSNs have helped people to communicate, breaking down the geographical barriers that restricted communication. Through social networks, virtual communication, sharing of information, community participation is possible even among people in uncomfortable conditions. Today, OSNs are one of the main parts of daily life by affecting sociality, but they are also important channels through which information travels faster than ever. Analysis of OSN can help to foresee events to manage critical scenarios. The rapid growth in popularity has opened new challenging problems which involve numerous fields in computer science. These issues have implications on social graph analysis, trust and security, and so on. Moreover, privacy issues and the usage of mobile devices has opened new research fields in the design of decentralised online social networks, which can be considered one of the most important challenges. Furthermore, the current improvement concerning the study and the proposal of new approaches for Social Networks and Media involve not only complex network analysis, and, in particular, the decentralisation of social services, but also the introduction of new AI solutions. 606 $aOnline social networks$vCongresses 615 0$aOnline social networks 676 $a006 700 $aGuidi$b Barbara$01385115 801 0$bNjHacI 801 1$bNjHacl 906 $aBOOK 912 $a9910574881403321 996 $aProceedings of the 2021 Workshop on Open Challenges in Online Social Networks$93432238 997 $aUNINA
