Menlo Park, Calif.—Google Inc. has upgraded its natural language search capabilities to respond to more complex, conversational queries.
The new search algorithm, dubbed Hummingbird by Google, is built on the company's Knowledge Graph technology unveiled last year. The technology displays or vocalizes intuitive query results based on natural language and crowd-sourcing, and is driven by voice as well as keyed-in queries. A query to see pictures of the Eiffel Tower, for example, could be followed by, “Show me pictures of the construction,” Google said in a statement.
The upgrade also includes a new comparison tool that responds to simple questions or directions, such as “compare butter with olive oil.” In the coming days, a reminder tool, responding to a “Remind me when it's time for ...” vocal command, for example, will automatically enter a notification date and then alert the user, the company said.
