On October 26th, one of Google’s senior research scientists Greg Corrado sat down with Bloomberg Business to discuss their new machine-learning Artificial Intelligence that’s changing the way Google handles search queries. “RankBrain” as it’s been named, has been slowly integrated since early 2015 and according to Corrado has now become the third-most important signal contributing to the result of a query.
According to the Bloomberg interview,
“RankBrain uses artificial intelligence to embed vast amounts of written language into mathematical entities — called vectors — that the computer can understand. If RankBrain sees a word or phrase it isn’t familiar with, the machine can make a guess as to what words or phrases might have a similar meaning and filter the result accordingly, making it more effective at handling never-before-seen search queries.”
This new leap forward builds off Google’s previous advances in improving search results with their “stemming” and “knowledge graph” and assists in processing new as well as complex or “long tail” queries; Google states that new queries make up about 15% of the 3 billion searches performed each day.
It’s important to note that RankBrain is not replacing Google’s Hummingbird algorithm or any part of it that we know: however, it has quickly become an important part of the way google processes its search queries.
