If we consider how Google is looking at entities, semantic search, and authorities, maybe we should consider Google's algorithms as parallel with Freebase. That's where they pull information for the Knowledge Graph.
"Freebase has over 39 million topics about real-world entities like people, places and things... Some topics are notable because they hold a lot of data (e.g., Wal-Mart), and some are notable because they link to many other topics, potentially in different domains of information."
Various types of information for different industries would mean various ways of analyzing them.
