TEMPO.CO, Jakarta - Social media giant Facebook has developed a fact-checking feature for its photos and videos to curb the spread of false and misleading news contents, according to Facebook product manager Antonia Woodford.
“Similar to our work for articles, we have built a machine learning model that uses various engagement signals, including feedback from people on Facebook, to identify potentially false content,” said Woodford in a written statement Tempo received on Saturday, September 15.
The photos and videos would then be sent to fact-checkers to be reviewed or fact-checkers can surface content on their own.

Antonia Woodford said that many of Facebook’s third-party fact-checking partners have expertise in 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.
According to her, Facebook utilizes other technologies to better recognize false or misleading contents, such as the optical character recognition (OCR) that works by extracting texts and photos and compare them to headlines from fact-checkers’ articles.
Facebook is also working on new ways to detect if a photo or video has been manipulated, but will mainly be manually reviewed by fact-checkers.
