Facebook says AI getting better at spying unwanted content

Facebook on Wednesday said that its software is getting more skilled at spying banned content at the social network, then working with humans to quickly remove terrorist videos and more. “While we err on the side of free expression, we generally draw the line at anything that could result in real harm,” Facebook chief executive Mark Zuckerberg said during a briefing on the company’s latest report on ferreting out posts that violate its policies.

“This is a tiny fraction of the content on Facebook and Instagram, and we remove much of it before anyone sees it.” Facebook has been investing heavily in artificial intelligence (AI) to automatically spot banned content, often before it is seen by users, and human teams of reviewers who check whether the software was on target.
