Alex Chitu at the Google Operating System Blog has noticed a new feature Google is testing in their search results – inline facts displayed underneath a search result listing.

It is unclear when Google decides to display these inline knowledge graph snippets.  For example, searching for “King of Rome” shows inline snippets, as does “King of France“, while “Queen of England” does not.

Chitu also points out that it is making some interesting assumptions regarding what information it displays, and it isn’t necessarily the most important information in regards to the individual search query.

Some of the facts aren’t very useful or are taken out of context. For example, Google shows “President: Dwight D. Eisenhower” next to the Wikipedia result for Richard Nixon, without mentioning that Nixon was vice president during the Eisenhower administration.

It is one of the many features and tests users spot Google running on a very regular basis.
