Google used AI and human moderation to take down over 75 million Google Maps reviews

Hundreds of millions of people contribute over 20 million reviews, ratings, and other pieces of content to Google Maps' over 200 million points of interest daily -- it's how the platform continues to grow so rapidly. But user contributions are intrinsically fraught. That's why increasingly, Google is using AI and machine learning to spot malicious contributions at submission time, ensuring they don't reach the over 1 billion users who regularly use Maps. In a blog post, Google said that it uses automated detection systems, including machine learning models, to scan millions of contributions to detect and remove policy-violating content. In the case of reviews, its systems audit every review before they're published to Maps, looking for signs of fake or misleading content.
