Google bets AI and human oversight will curb online extremism

Google is under a lot of pressure to stamp out extremists' online presences, and it's responding to that heat today. The internet giant has outlined four steps it's taking to flag and remove pro-terrorism content on its pages, particularly on YouTube. Technological improvements play a role, of course, but the company is also counting on a human element that will catch what its automated filters can't. To start, it's pouring more energy into machine learning research that could improve its ability to automatically flag and remove terrorist videos while keeping innocently-posted clips (say, news reports) online. It's also expanding its counter-radicalization system, which shows anti-extremist ads to would-be terrorist recruits.
