Facebook is Now Using AI to Detect Fake News



Following the discovery that foreign parties used Facebook to spread misinformation during the US' 2016 presidential elections, the platform has promised to eradicate the issue over time.

It seems the company's hard work in this regard is finally beginning to bear fruit - in a blog post published today, Facebook's Product Manager Antonia Woodford discussed some of the major changes the company has made to reduce the spread of "false news."

Facebook has already taken the first steps towards accomplishing their goal by partnering with several third-party fact-checkers. These individuals review and rate the accuracy of various pieces of content, including captioned images, and videos.

In fighting against fake news in Facebook yesterday Facebook Product Manager, Antonia Woodford said.

We know that people want to see accurate information on Facebook, so for the last two years, we’ve made fighting misinformation a priority. One of the many steps we take to reduce the spread of false news is working with independent, third-party fact-checkers to review and rate the accuracy of content. To date, most of our fact-checking partners have focused on reviewing articles. However, we have also been actively working to build new technology and partnerships so that we can tackle other forms of misinformation. Today, we’re expanding fact-checking for photos and videos to all of our 27 partners in 17 countries around the world (and are regularly on-boarding new fact-checking partners). This will help us identify and take action against more types of misinformation, faster.

They have built a machine learning model that uses various engagement signals, including feedback from people on Facebook, to identify potentially false content. They also send those photos and videos to fact-checkers for their review, or fact-checkers can surface content on their own. Many of our third-party fact-checking partners have expertise evaluating photos and videos and are trained in visual verification techniques, such as reverse image searching and analyzing image metadata, like when and where the photo or video was taken. Fact-checkers are able to assess the truth or falsity of a photo or video by combining these skills with other journalistic practices, like using research from experts, academics or government agencies
