Google is building the largest store of information in human history - a knowledge base that autonomously gathers and merges data from across the web to provide unprecedented access to all facts about the world.
The search giant is building Knowledge Vault, a type of knowledge base - a system that stores information so that machines as well as people can read it.
Google's existing knowledge base, called Knowledge Graph, relies on crowdsourcing to expand its information
However, humans could only take it so far so Google decided to automate the process.
It started building the Vault by using an algorithm to automatically pull in information from all over the web, using machine learning to turn the raw data into usable pieces of knowledge.
