Facebook using artificial intelligence to help suicidal users

Facebook has started using artificial intelligence to identify users who are potentially at risk of committing suicide. The social network has developed algorithms capable of scanning posts and comments for warning signs. These could be phrases such as "Are you okay?" or "I'm worried about you", or more general talk of sadness and pain. The AI tool would send such posts to a human review team, which would get in touch with the user thought to be at risk and offer help, in the form of contact details for support services or a chat with a member of staff through Facebook Messenger. The site had previously relied on other users reporting worrying updates.
