In early February 2017, Facebook demonstrated a natural language picture research engine, which, as a long article on the Facebook Code blog explains, enables users to find photographs without using specific keywords but simply by describing what appears in them.
The new tool does not uniquely rely on descriptions accompanying photos posted on the social network, but on a wide range of elements identified by its “Lumos” artificial intelligence system. The plan is to extend this technology to video sequences in the near future.
