What is Google's Knowledge Graph ?

Google has unveiled the Knowledge Graph, which they’re calling the “first step in the next generation of search.” The initial release is gradually rolling out to U.S. English users and consists of three elements:

• Links to different sets of results based on contextual meanings for any given search term
• Topic summaries with key facts visible in the sidebar of the SERPs
• “Information boxes” that offer additional information in the SERPs sidebar based on popular related queries.

Google simultaneously announced in a separate blog post that Knowledge Graph for mobiles and tablets is in the works, with Android 2.2+ and iOS4+ versions rolling out right now.
