At Meta, we have both hand-crafted and learned risk models to flag questionable content, for humans to review. To operationalize these, we aggregate the different models to give a single ranking score, calibrating them to prioritize more reliable risk models. But violation trends change over time, affecting which risk models are most reliable; risk models change; and novel models are introduced. To continuously update the system in response to such trends, we use a contextual bandit. Our approach increases Meta&#8217;s top-line metric for measuring the effectiveness of its content moderation strategy by 13%.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><\/p>\n\n\n\n<hr class=\"wp-block-separator has-text-color has-vivid-cyan-blue-color has-alpha-channel-opacity has-vivid-cyan-blue-background-color has-background is-style-wide\" \/>\n\n\n\n<p><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Presented by Deeksha Sinha, Research Scientist at Meta What tech lies behind the social media giants&#8217; attempts to keep content &#8221;within the rules&#8221;?
