RankBrain
RankBrain is a machine learning artificial intelligence system confirmed to be used by Google on 26 October 2015. It helps Google to process search results and provide more relevant search results for users. ==What does RankBrain do?== RankBrain uses artificial intelligence to embed vast amount of language into mathematical entities called vectors. 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.〔(【引用サイトリンク】url=http://news.surgogroup.com/google-turning-lucrative-web-search-ai-machines/ )〕 As the exact function of Google algorithm components are not fully disclosed it is impossible to know with 100% certainty. The general consensus is that RankBrain interprets the user searches to find pages that may not have contained the exact words that were used in the user search query. When offline, RankBrain is given batches of past searches and learns by matching search results. Once RankBrain's results are verified by Google's team the system is updated and goes live again.
