Google Gets Smarter
So, instead of just analyzing keywords and matching strings of characters with their index to return search results that are likely relevant to your keywords, Google will now put your keywords into a context, allowing it to understand the thing your looking for in the real world.
Google's "Knowledge Graph" is drawing on many sources of information to understand things in the real world as "objects" rather than strings of data. It's also starting to piece together relationships between objects.
