Users' privacy at risk? Facebook 'labels' posts manually in India

Human-powered content labeling, also referred to as 'data annotation,' is a growth industry as companies seek to harness data for AI training and other purposes.

Business Standard : Over the past year, a team of as many as 260 contract workers in Hyderabad, India has ploughed through millions of Facebook Inc photos, status updates and other content posted since 2014.

The workers categorize items according to five "dimensions," as Facebook calls them.

These include the subject of the post - is it food, for example, or a selfie or an animal? What is the occasion - an everyday activity or major life event? And what is the author's intention - to plan an event, to inspire, to make a joke?

The work is aimed at understanding how the types of things users post on its services are changing, Facebook said. That can help the company develop new features, potentially increasing usage and ad revenue.

Details of the effort were provided by multiple employees at outsourcing firm Wipro Ltd over several months. The workers spoke on condition of anonymity due to fear of retaliation by the Indian firm. Facebook later confirmed many details of the project. Wipro declined to comment and referred all questions to Facebook.

The Wipro work is among about 200 content labeling projects that Facebook has at any time, employing thousands of people globally, company officials told Reuters.

Many projects are aimed at "training" the software that determines what appears in users' news feeds and powers the artificial intelligence underlying many other features.

The labeling efforts have not previously been reported.

"It's a core part of what you need," said Nipun Mathur, the director of product management for AI at Facebook. "I don't see the need going away."

The content labeling program could raise new privacy issues for Facebook, according to legal experts consulted by Reuters. The company is facing regulatory investigations worldwide over an unrelated set of alleged privacy abuses involving the sharing of user data with business partners.

The Wipro workers said they gain a window into lives as they view a vacation photo or a post memorializing a deceased family member. Facebook acknowledged that some posts, including screenshots and those with comments, may include user names.
