Factbox: The work at one Facebook ‘labelling’ project

Facebook Inc has thousands of content labellers around the world who categorise content with the aim of creating large datasets that can be more readily analysed by humans and software.

One project at outsourcing vendor Wipro Ltd in Hyderabad, India, has seen as many as 260 workers over the last year look through a random selection of user-posted images, videos and status updates since 2014.

Facebook said the project aims to uncover how usage of its flagship social media service has evolved, potentially informing decisions about new products. Facebook provided the five questions, or “dimensions” as the company calls them, that the Wipro labelers must address about each piece of content shown to them.
