 Analysing the language used and the spread of information through a network, as well as the spatial and temporal context of the information, is used to build a real-time lie detector for social media.This will help, for example, emergency services (who already integrate social media as part of their alerting and response systems) to flag potential hoax emergencies.Evaluating the authority of sources automatically is also a project goal, based on the treatment of the news and information that comes from them.
