Jack Menzel, director of product management at Google, told CNN in an interview, “The web pages we [currently] return for the search ‘kings,’ they’re all good.”
“You, as a human, associate those words with their real-world meaning but, for a computer, they’re just a random string of characters.”
By using Knowledge Graph, the result for your keyword would be separated according to categories. For example, if you Google a word ‘letter’, the search engine would separate the findings in categories like ‘alphabetical letter’ or a letter that you write (maybe love letter). So by clicking on a particular box you will only results related to the specific findings.
“It hones your search results right in on the task that you’re after,” Menzel said.
“More specific searches, say for the name of a celebrity, will render boxes with basic information, as well as links to what Google believes are possibly related searches,” CNN adds.
