New York (The Verge) — YouTube brings back more human moderators after AI systems over-censor theverge.com/2020/9/21/2144….
YouTube is bringing back furloughed human moderators after its AI systems proved to be over-zealous in removing content. As reported by the Financial Times, the use of AI moderators during the middle of the year led to an increased number of video removals and appealed takedowns.
Back in March, YouTube said it would rely more on machine learning systems to flag and remove content that violated its policies on things like hate speech and misinformation. But YouTube told the Financial Times this week that the greater use of AI moderation had led to a significant increase in video removals and incorrect takedowns.
Around 11 million videos were removed from YouTube between April and June, says the FT, or about double the usual rate. Around 320,000 of these takedowns were appealed, and half of the appealed videos were reinstated. Again, the FT says that’s roughly double the usual figure: a sign that the AI systems were over-zealous in their attempts to spot harmful content.
This admission of failure is notable. All major online social platforms, from Twitter to Facebook to YouTube, have been increasingly under pressure to deal with the spread of hateful and misleading content on their sites. And all have said that algorithmic and automated filters can help deal with the immense scale of their platforms. — James Vincent/@verge
