YouTube has made significant changes to its hate speech policy and removed over nine million videos in the last quarter as part of an ongoing process to reduce the spread of harmful content, Google's Indian-American CEO Sundar Pichai said Monday, but acknowledged that the platform is too big to completely fix the problem.
YouTube, which is owned by Google, has come under fire in the last couple of years, as controversial and supremacist content has continued to show up on the site despite the company's attempts to filter it out.
"We work hard to get right, and every few years we feel the need to evolve them because we see changes in how the platform is getting used, Pichai said in response to a question from CNN.
"Just last week, we had significant revisions to our hate speech policy (which) appear(ed) to be very focused on removing harmful content and reducing the spread of what we think of as borderline content," he said.
"Just last quarter, we removed over nine million videos. And so, it's an ongoing process, but there's more we need to do and we acknowledge that, Pichai said.
When asked whether there will ever be enough humans to filter through and remove such content, Pichai said, "We've gotten much better at using a combination of machines and humans."
"So it's one of those things, let's say we're getting it right 99 per cent of the time, you'll still be able to find examples. Our goal is to take that to a very, very small percentage well below 1 per cent."
When asked why it took them seven years to realise that those videos should not be up and ads should not be running next to those videos, Pichai said, "It's heartbreaking for sure and, all of us would look back and we wish we had gotten to the problems sooner than we did."
