Horizon 2020 Project IMPETUS
IMPETUS will detect potential threats by using AI techniques to search social media and the deep/dark web for unusual and suspicious activities, and to analyse available smart city data. Threats will be classified and assessed to determine an appropriate response using a human-in-the-loop approach to combine the strengths of AI and human judgement.
