Google says AI better than humans at scrubbing extremist YouTube content

Company pledges further development to tackle rise of extremist and illicit content and hate speech, but says advanced machine learning is the answer

Google has pledged to continue developing advanced programs using machine learning to combat the rise of extremist content, after it found that it was both faster and more accurate than humans in scrubbing illicit content from YouTube.

The company is using machine learning along with human reviewers as part of a mutli-pronged approach to tackle the spread of extremist and controversial videos across YouTube, which also includes tougher standards for videos and the recruitment of more experts to flag content in need of review.
