## MOTIVATION AND RATIONALE
Today, Social Media 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. 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 have opened new research fields in the design of decentralized 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 involves not only complex network analysis, and, in particular, the decentralization of social services, but also the introduction of new AI solutions.
The workshop targets researchers, doctoral students, people from industry and other people interested in discussing, reflecting and networking on central themes associated with the development and the use of social networks.
