The UK government has unveiled a tool it says can accurately detect jihadist content and block it from being viewed.
Home Secretary Amber Rudd said she would not rule out forcing technology companies to use it by law. Ms Rudd is visiting the US to meet tech companies to discuss the idea, as well as other efforts to tackle extremism.
Thousands of hours of content posted by the Islamic State group was run past the tool, in order to «train» it to automatically spot extremist material.
The government provided £600,000 of public funds towards the creation of the tool by an artificial intelligence company based in London.
ASI Data Science said the software is capable of detecting 94% of IS’s online activity, with an accuracy of 99.995%. Anything the software was not sure about would then be flagged up for a human decision to be taken.
It is intended to lighten the moderation burden faced by small companies that may not have the resources to effectively tackle extremist material being posted on their sites.
