Fighting Fake News: Facebook to Fact-Check Photos and Videos
In a bid to curb the spread of misinformation, social networking giant Facebook is now expanding its fact-checking capabilities to all of its third-party analysis partners around the world to examine the authenticity of the photos and videos shared on the platform.
Based on testing and research, the social networking company claimed that misinformation in photos and videos falls into three categories – manipulated or fabricated, out-of-context and text or audio claim – which the platform aims to monitor and reduce.
According to Facebook’s Product Manager Tessa Lyons, the company started its work on misinformation with articles after users in the US said it was the most prevalent form of false news they were seeing.
Expanding the fact-checking capabilities of Facebook to third-party partners would add more ratings on the accuracy of the content circulating on the platform, which would make it easier to improve the credibility of Facebook's ML model.
We have built a Machine Learning (ML) model that uses various engagement signals, including feedback from people on Facebook, to identify potentially false content and then send to the fact-checkers for review who analyse the content metadata along with other information to assess the truth or falsity of a photo or video by combining these skills with other journalistic practices or government agencies.Facebook Statement
“We use optical character recognition (OCR) to extract text from photos and compare that text to headlines from fact-checkers' articles and now we are also working on new ways to detect if a photo or video has been manipulated,” the company added.
Photos and videos have become the fulcrum around which fakes news gets circulated via social media. With many countries slated to hold elections in 2019, it’s likely that Facebook doesn’t want to drag itself into another Cambridge Analytica-like episode ever again.
