Some recent news coverage about Google has sparked interest in where we are and where we're headed in search.

Let me just say that every day, we're improving our ability to give you the best answers to your questions as quickly as possible. In doing so, we convert raw data into knowledge for millions of users around the world. But our ability to deliver this experience is a function of our understanding your question and also truly understanding all the data that's out there. And right now, our understanding is pretty darn limited. Ask us for “the 10 deepest lakes in the U.S,” and we'll give you decent results based on those keywords, but not necessarily because we understand what depth is or what a lake is.

In 2010, we acquired Freebase, an open-source knowledge graph, and in the time since we've grown it from 12 million interconnected entities and attributes to over 200 million. Our vision for this knowledge graph is as a tool to aid the creation of more knowledge -- an endless cycle of creativity and insight.

But as I explained in an interview last month (http://mashable.com/2012/02/13/google-knowledge-graph-change-search/), our initial steps towards this virtuous cycle are indeed baby steps. So stay tuned for updates on what will continue to be a long road ahead.
