Google has revamped its search engine in an attempt to offer instant answers to search questions.
A new function, the Knowledge Graph, will make the site's algorithms act "more human", the site said in a blog post.
The feature will at first be available to US-based users, but will be rolled out globally in due course.
It follows similar efforts by rival Bing to provide added search content beyond the typical list of links.
Microsoft's search engine launched its "snapshot" column last week as part of a wider site redesign.
Google's senior vice president of engineering Amit Singhal explained
that, until now, the search engine was only able match keywords, rather
than understand context.
Mr Singhal said the words "Taj Mahal" could mean different things to different people.
"You might think of one of the world's most beautiful monuments, or a
Grammy Award-winning musician, or possibly even a casino in Atlantic
City, NJ. Or, depending on when you last ate, the nearest Indian
restaurant," he said.
Key information
Google said the Knowledge Graph has been programmed to use around 3.5
billion different attributes to organise results meaning it can now
group results according to those various alternative interpretations.
For some searches, such as on prominent people, Google will
automatically pull up a summary box with key information on that topic.
The next step, Mr Singhal said, is to look at how the site can answer
more complex questions, such as "What are the 10 deepest lakes in
Africa?"
In doing so the search engine would need to draw on multiple sources and factor in many different criteria.
This kind of computational, intelligent search is currently pioneered by
the likes of Wolfram Alpha - a site which gathers verified data, such
as from the World Health Organization, to provide statistical results.
It has long been a technological goal to produce search engines that could react entirely naturally to human-like queries.
One such effort includes the somewhat iconic search engine Ask Jeeves,
where users can ask a stereotypically English butler for help.
