As Drew Olanoff puts it: “Google’s Knowledge Graph has become a handy tool when you’re searching for things that interest you. There are a few reasons why it’s a handy feature, but most of all it provides context to what you’re searching for.”
Here’s how Google describes it: “Last month, we showed how you can now get answers to your questions with the help of the Knowledge Graph even when the best answer is not just a single person or thing, but a collection or list of items. When looking for [cedar point rides], you see a carousel of popular roller coasters at the amusement park, drawing on our Knowledge Graph and the collective intelligence of the Web. The feature was initially available in English on google.com, and we’re now taking our first steps to make it available more widely around the world.” The company is rolling out the carousel for “factual lists to English users on all Google domains across the world.”
