That was the time, in the prehistory of about 1995, when our ideas of "search" still carried the sense of the word's Latin roots – a search was a kind of "arduous quest" ...
Until now, Google has been an unprecedented signposter of knowledge. It has not "known" the answer to anything itself but it has had an awfully clever way of directing you to exactly the place you can find out...
"the semantic web", the version that had understanding as well as data, that could itself provide answers, not links to answers...Thus, when you type "10 Downing Street" into Google with Knowledge Graph, it responds to that phrase not as any old address but much in the way you or I might respond – with a string of real-world associations, prioritised in order of most frequently asked questions.
Google has already come closer than anyone could ever have imagined to the "nothing was left to be collected" part of that equation. It is in searchable possession not only of the trillions of pages of the world wide web, but it is well on the way to photographing all the world's streets, of scanning all the world's books, of collecting every video ...This data has been collected not just for the purpose of feeding it back to us as accurately as possible, but also for the wider purpose: of teaching Google how to think for itself.
Search analysis is divided into "long clicks" and "short clicks". ... A short click ...occurs when a user performs a search, clicks through on a result and quickly comes back to the result set to click on an alternative result.
"We are maniacally focusing on the user to reduce every possible friction point between them, their thoughts and the information they want to find." - Amit Singhal
