Facebook connects people, but it also wants to know them so it can show relevant information and targeted ads to them. To generate a personalized feed for each user, the network needs to identify and classify content in posts, images and news. Towards that end, the company launched an ambitious AI plan, and a research laboratory, at the end of 2013. Today at F8, its annual developer's conference, the network's CTO Mike Schroepfer talked about a specific AI prototype that can identify content in videos and the context of words. While AI for video can identify 487 types of sport activities, another reads sentences to pinpoint possessives from the grammar used. This allows the company to sift through an overwhelming load of information so it can arrive at a newsfeed that's most appropriate for the user. It's unclear if the new system is already peeking through posts, but Schroepfer indicated that over the next 10 years, Facebook will focus on building advanced AI systems.
