At the end of a week when we've been looking at the development of artificial intelligence (AI), we examine how effective computers can be in tracking suspected sex offenders - or terrorists. The head of MI5 told us this week that the terrorist threat is at its highest level since 9/11. Our security correspondent, Gordon Corera, has been hearing about one British company - founded by people with a background in government and intelligence - to see what its AI technology can do.
An artificial intelligence startup , Ripjar , uses natural language processing and machine learning to analyse huge sets of data , to understand and learn patterns within the data . The comprehensive data platform can be configured by government agencies , such as NSA , to look for activity of terrorist groups or bomb threats on social media sites like Twitter . The platform can also look at who is sharing the data and can detect any activity associated with the time the data was shared , and the activity of terrorist groups around the world .
