Google introduced what it calls its “Knowledge Graph,” designed to “understand real-world entities and their relationships to one another: things, not strings.” According to the blog post from Amit Singhal, Google senior vice president of engineering, the Google Knowledge Graph is “an intelligent model-in geek-speak, a ‘graph’-that understands real-world entities and their relationships to one another: things, not strings. Google’s Knowledge Graph isn’t just rooted in public sources such as Freebase, Wikipedia, and the CIA World Factbook. It’s also augmented at a much larger scale-because we’re focused on comprehensive breadth and depth. It currently contains more than 500 million objects, as well as more than 3.5 billion facts about and relationships between these different objects. And it’s tuned based on what people search for, and what we find out on the web.”
As stated on the Google website : When you search, you’re not just looking for a webpage. You’re looking to get answers, understand concepts and explore…So we’re building a Knowledge Graph: a huge collection of the people, places and things in the world and how they’re connected to one another.
