Isis videos targeted by artificial intelligence that can detect propaganda before it's uploaded

Artificial intelligence technology that can detect Isis videos and prevent them from being uploaded is being released to stop the spread of the "poisonous" material. Developers funded by the Home Office are sharing their software for free with any website or app in the world in the hope it will make the terrorist group's propaganda harder to access and share. Tests suggest it can detect 94 per cent of Isis videos and makes so few mistakes that a single person could moderate borderline cases for the whole of YouTube. Dr Marc Warner, chief executive of ASI Data Science, told The Independent the technology's success depends on how many companies build it into their systems but "we hope that this can play its part in removing extremist content from the web". "Lone-wolf attacks are hard to spot with conventional surveillance – it is a difficult problem if someone is radicalised in their bedroom," he added.
