Abstract: Disinformation is a known issue that can be “weaponised” by malicious actors to sway opinions during key events (e.g. elections, wars, etc.). Although a significant amount of NLP research has been developed for supporting journalists in debunking false narratives, other sectors like police authorities are not well equipped to deal with disinformation. Disinformation that can cause harm to security is a growing issue, where the police need to deal with events prompted and amplified by false narratives. In this talk, I will talk about our work at the VIGILANT project (, that aims to develop tools and training materials to support police officers in dealing with false narratives that can, for instance, cause civil unrest.
