RankBrain is an artificial intelligence system that’s being applied to and used with Google’s current search engine algorithms to provide better results to user queries. Rooted in machine learning, RankBrain will use mathematical processes and an advanced understanding of language semantics to gradually learn more about how and why people search, and apply those conclusions to future search results. Rather than being pre-programmed to respond to certain situations in a specific, pre-determined way (like Google search has been up until now), it can update itself over time. Think of it as a robot that can constantly scour for better parts to upgrade itself with rather than relying on an outside human for occasional maintenance.
