Google Adding Explanations to Knowledge Graph

Google is adding explanations to Knowledge Graph panels, where applicable. The explanations, which appear when a user hovers over images in the “People also search for” section, offer more information on how two subjects are connected.

In the product announcement, Google uses the movie "Gone With the Wind" as an example. Hovering over icons people also search for, in this case "The Wizard of Oz", displays an explanation that Victor Fleming directed both movies.

It can also be used to indicate familiar or professional associations, as in the case of a search for actress Sandra Bullock. Keanu Reeves appears in the “People also search for” section of the Knowledge Graph panel for Sandra Bullock. Google now explains, “Sandra Bullock and Keanu Reeves both appear in The Lake House and Speed.”
