Google Knowledge Graph

Microsoft might have recently deployed a "better than ever" Bing, but if you think Google wouldn't be resting on its laurels... you're right. Google has been working on making its search engine more powerful, and that's precisely what we're about to get thanks to Google's new knowledge graph

For a long time, search engines searched "text". Meaning, if you search for something like "Taj Mahal", you'd get results from lots of pages, whether it was referring to the world famous monument, the musician, a indian restaurant, a casino, or any other stuff containing it.

Now, Google will get to know individual entities, and allow you to narrow down your results to exactly what you're looking for. This knowledge graph now contains 500 million objects and 3.5 billion facts and relationships between them... and will grow even more from now on.

What can you exepect from this Knowledge Graph? According to Google

1. Find the right thing
Language can be ambiguous—do you mean Taj Mahal the monument, or Taj Mahal the musician? Now Google understands the difference, and can narrow your 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.

2. Get the best summary
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.

3. Go deeper and broader
Finally, the part that’s the most fun of all—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. Do you know where Matt Groening, the creator of the Simpsons (one of my all-time favorite shows), got the idea for Homer, Marge and Lisa’s names? (hint: check his parents and siblings names).

The new Knowledge Graph view is currently being rolled out to U.S. English users. (And we hope the rest of the world will soon follow!)
