Your search experience is about to get a whole lot better as Google just unveiled one of its most significant updates to its search engine: the Knowledge Graph.

In March, Google announced its plan to provide you with more relevant results through semantic search — which refers to the process of understanding the meaning of words.

Previously, if you searched for “kings,” Google didn’t know if you meant royalty, a sports team, or a TV series, so it displayed results for all of them. Moving forward, a box will appear and you will be asked to clarify your search and your results will be filtered based on your answer.

Once Google knows what you’re looking for, that box will become a resource itself, including descriptions and relevant key facts. If Google gets something wrong, you can report a problem directly from the box. The company will monitor corrections and update its database to prevent future errors. It will also generate a report for outside data sources like Wikipedia.

Going back to our example in our previous report: If you search for “the tallest buildings in the U.S.,” Google will not only understand your request, but will also return a more valuable list, including the height, location, and history for each building.

It’s important to note that this update will have little effect on Search Plus Your World. When you search for someone, the Knowledge Graph will identify Google+ Profiles as that person, but that’s about it for now.

Google’s Knowledge Graph is rolling out to English-language U.S. users on desktop, mobile, and table searches. Native Google Search apps and additional countries and languages are coming soon.
