Google to roll out Knowledge Graph globally & add Gmail content to search

Google has announced several changes it has introduced to "make search even more intelligent," including the global expansion of its Knowledge Graph feature to all English-speaking users.

Knowledge Graph, which first launched in May, is a Bing-like snapshot panel that appears to the right of search results showing facts related to a user's search query. The feature will expand to users across the world, as long as they are searching in English, Google announced.

With the global expansion, Google intends to present users with relevant information based on their location. A search for the term "chiefs," for example, would yield information about the football team the Kansas City Chiefs in the US, for instance. Those searching in Australia, meanwhile, would see information about the Chiefs rugby team.

Also, Google will now include a new interactive carousel showing relevant lists and collections for certain queries (see photo below). Searching for "museums in NYC," for example, will offer up a browsable list at the top of the search results page showing the museums in New York. This feature is especially helpful because users aren't always searching for a single topic, and might be looking for a list or collection of things, Google said.

"So far we can produce hundreds of thousands of lists involving millions of items, and we'll keep growing to match your curiosity," Amit Singhal, senior vice president of Google Search, wrote in a blog post.

Meanwhile, Google is also adding some users' personal Gmail messages to their search results as part of a "limited trial," the Web giant announced. When a participating user types a search query into Google, they will see related information from their personal emails on the right column.

"Sometimes the best answer to your question isn't available on the public web — it may be contained somewhere else, such as in your email," Singhal wrote. "We think you shouldn't have to be your own mini-search engine to find the most useful information — it should just work."

Those who are interested in this capability can sign up to participate in the field trial.

Finally, Google is adding voice-based answers to its mobile app for the iPad and iPhone. With the forthcoming version of the Google Search App, users will be able to speak a question out loud and the app will, in some cases, speak the answers back – similar to Apple's voice-activated personal assistant Siri. This feature has been available on Android for a few weeks, and Google promised to add it to the iOS app soon.
