Google Knowledge Graph, begun rolling out today to U.S. English users on desktop, smartphones and tablets mobile devices, help you discover new information quickly and easily is a new way to handle queries that replaces keywords with objects.
"The Knowledge Graph enables you to search for things, people or places that Google knows about--landmarks, celebrities, cities, sports teams, buildings, geographical features, movies, celestial objects, works of art and more--and instantly get information that's relevant to your query. This is a critical first step towards building the next generation of search, which taps into the collective intelligence of the web and understands the world a bit more like people do," explains Google.
For now, you'll only notice a new info pane in the right sidebar that shows more information about your query.
Here is how Knowledge Graph enhances Google Search:
Google now understands disambiguate queries, and can narrow search results just to the one you mean--just click on one of the links to see that particular slice of results. "This is one way the Knowledge Graph makes Google Search more intelligent--your results are more relevant because we understand these entities, and the nuances in their meaning, the way you do," Google said. For example, when searching for [Taj Mahal], you could mean Taj Mahal the monument, or Taj Mahal the musician, Google now understands the difference.
"With the Knowledge Graph, Google can better understand your query, so we can summarize relevant content around that topic, including key facts you're likely to need for that particular thing. For example, if you're looking for Marie Curie, you'll see when she was born and died, but you'll also get details on her education and scientific discoveries. The Knowledge Graph also helps us understand the relationships between things. It's not just a catalog of objects; it also models all these inter-relationships. It's the intelligence between these different entities that's the key," explained Google.
Finally, the Knowledge Graph can help you make some unexpected discoveries. You might learn a new fact or new connection that prompts a whole new line of inquiry.
Google's graph has 500 million objects and 3.5 billion facts. For any generated query, Google now shows a small thumbnail, a snippet from a Wikipedia article, a few relevant facts and some related queries on the search results. It's just like a Wikipedia infobox automatically generated using data from the Web and that's smart enough to only show important facts and hide the things people won't need.
"On wireless networks and on small screens, every page load and every pixel matters when it comes to speed and ease-of-use. So we strive for efficiency and try to make the most of touch-based interactions when integrating information from Knowledge Graph into our mobile and tablet search experiences. Tapping or swiping on the content from the Knowledge Graph instantly shows more useful information. When searching on tablet, you can swipe the rows of images to explore more related content. For example, say searching for [andromeda], which could be the galaxy, the TV series, or the Swedish band. The Knowledge Graph distinguishes between each of these meanings and shows an interactive ribbon at the top of the search results that you can swipe and tap to select just what you're looking for," explained Google.
These features are currently rolling out to most Android 2.2+ and iOS4+ devices. On Android, the feature is available through Google in the browser and the Quick Search Box. On iOS, the feature is available in the browser and will be coming soon to the Google Search App.
