Facebook's AI is still largely baffled by covid misinformation – MIT Technology Review

The news: In its latest Community Standards Enforcement Report, released today, Facebook detailed the updates it has made to its AI systems for detecting hate speech and disinformation. The tech giant says 88.8% of all the hate speech it removed this quarter was detected by AI, up from 80.2% in the previous quarter. The AI can remove content automatically if the system has high confidence that it is hate speech, but most is still checked by a human being first. Behind the scenes: The improvement is largely driven by two updates to Facebook's AI systems. First, the company is now using massive natural-language models that can better decipher the nuance and meaning of a post.
