OASIS'23: 3rd International Workshop on Open Challenges in Online Social Networks

Online Social Networks (OSNs) became part of everyday life for many people around the world. They are one of the main channels through which information can spread at lightning speed. Thanks to this fact, people use them for the most disparate reasons, such as sources of information in place of newspapers, to receive emotional or technical support, or to share their ideas and opinions to satisfy their need for sociality. Since their introduction, people questioned these services because they are affected by several problems. These problems include the preservation of the users' privacy, fake news diffusion, diffusion of illegal pieces of content, censorship vs free speech, economic value redistribution, security vs trust, and so on. The aim of this workshop is to partially try to overcome these problems by setting up a platform for researchers to publish their contributions. The contributions can point to innovative methods and algorithms for social graph mining, which can be helpful to develop more efficient information diffusion techniques; the problem of privacy, and how can be enforced in these systems is current, and in particular the relation between security, trust and privacy is crucial in the scenario of OSNs; the decentralisation and its impact on the implementation of social services; how Artificial Intelligence techniques that respect the privacy of the users can be implemented; technologies that enable the metaverse.
