Google bets AI and human oversight will curb online extremism

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. Google plans to "greatly increase" the number of humans in its YouTube Trusted Flagger program, improving the chances that it'll catch terrorist material. Google wants to tackle those YouTube videos that are borderline, too -- if it spots videos with "inflammatory" religious or supremacist material, it'll put those clips behind a warning and prevent them from getting ad revenue, comments or viewing recommendations.
