Launched by Google on 26th October 2015, RankBrain accounts for an Artificial Intelligence (AI) system which provides aid to Google to process its search queries through algorithm-learning program.

The uniqueness of this machine-learning technology lies in its effective management of search queries that are new to the Google search engine.

By converting the search language into vectors (mathematical codes), this AI system can conjecture what the users are trying to convey by exploring already recorded search phrases of similar meaning and filter search results accordingly without any manual help.
