The Growth of Google’s Knowledge Graph
February 15, 2014
The article titled How a Database of the World’s Knowledge Shapes Google’s Future on MIT Technology Review is an explanation of Google’s Knowledge Graph and the progress made in compiling information to feed into it. The Knowledge Graph began as a database built by Metaweb, which Google acquired in 2010. The article is an interview with Metaweb cofounder and Google employee John Giannandrea, who explains the Knowledge Graph through an analogy with maps.
“For a maps product you have to build a database of the real world and know there are things called streets, rivers, and countries in the physical world. That’s creating a symbolic structure for the physical world; the Knowledge Graph does that for the world of ideas and common sense. We have entities in the knowledge graph for foods, recipes, products, ideas in philosophy or history, and famous people.”
The difference between the old web search and the Knowledge Graph version is what is understood. As the amount of data grows, the effectiveness of search is also supposed to improve. The article skims over the ad revenue drive of the Knowledge Graph, but it is clear that the better Google is at recognizing meaning in searches, the better they will be able to “target search ads”.
