Facebook builds AI system to understand memes

Facebook's new Rosetta AI can read memes Facebook's new Rosetta AI can read
Katie Ramirez | 14 September, 2018, 11:43

Rosetta has been trained on a vast data set of what Facebook calls "human-annotated" public images with text and their locations and also text on wider public images such as posters and menus. Memes have become a great source to entertain people, convey a message or any other objective on the social media platform.

Facebook says that Rosetta has already been widely adopted within various teams at the company and with Instagram, and noted that the text extracted from images is also being used in various machine learning models, such as those to improve its photo searching features. Facebook, in particular, uses an army of moderators that help it weed out offensive content shared on the platform. After that, it analyzes each of the detected regions using a conventional neural network (CNN) to recognize and transcribe words contained within them.

Facebook has over two billion users and monitoring all the content posted daily is virtually impossible.

Fb says text extraction and machine learning are being set up to exercise to "robotically identify squawk that violates our hate-speech coverage" and that it's doing so in just a few languages. However, Rosetta is very different from all the tools used in the past.

One of the largest social media platform Facebook Inc.'s has around more than 2.2 billion users share a staggering number of photos and videos on the platform each day that the social giant needs to catalog, add to search results and scan for harmful content.

To handle this monumental task, the company has built a sophisticated artificial intelligence which is known by the name as Rosetta.

Facebook has struggled in the past to adequately identify hate speech or misleading information and in documents seen by Motherboard, Facebook's own training material incorrectly said that an image of the 2010 quake in Jeiegu, China was a picture of a Myanmar genocide. The AI tool will be effective enough to understand multiple languages. It helps to determine how the Newsfeed as well as for the offensive content. Rosetta is the most recent advancement. The problem with automatically spotting hate speech on the platform via certain phrases is that people adapt.
