What is her presentation about:
This presentation investigates several issues of using AI techniques to analyze social data in order to detect threats in the cyberspace. Social data is understood as information collected from social media, including a wide range of networks and platforms that show what online users publish on those platforms but also how they share, view or engage with content or other users. First, we will analyze how the virtual domain of cyberspace is unlike the environmental domains of air, land, maritime and space and how it challenges traditional understanding of concepts such as temporality, conflict, information, border, community, identity or governance. Several specific phenomena will be considered: opacity and information filtering (echo chambers, bubble filters), disinformation campaigns (fake news, propaganda, hoaxes, site spoofing), misleading intentions (data leaks), biased interactions (social boots, smoke screening). The discussion is based on practical illustrations of social data analysis, tackling fake news propagation in the aftermath of terrorist attacks and the propagation of extremist ideologies online. The presentation concludes by illustrating the state of art on tools and techniques for cyberspace exploration along with several ongoing research projects, while also leaving room for discussion.
