---- Google's Second Brain - The Knowledge Graph and the Evolution of Search

i dont anything exciting in that article. take this little bit as an example...
Today, when you enter a search term into Google, the company kicks off two separate but parallel searches. One runs against the traditional keyword-based Web index, bringing back matches that are ranked by statistical relevance—the familiar “ten blue links.” The other search runs against a much newer database of named entities and relationships.
Type in the query “Philadelphia,” and this second search will produce a new “knowledge panel” in the right-hand margin of the results page, complete with a map and other basic facts about the city William Penn founded. (Hedging its bets, however, Google will also include a thumbnail of the movie poster from the 1993 Tom Hanks film Philadelphia.) To use Google’s own description, the new database helps the search engine understand “things, not strings.”
This second brain is called the Knowledge Graph.
to a cynic like me, i would look at that and just say this: when people search for "philadelphia", most of them end up clicking on links to do with the city, rather than the movie. google knows this, and that is why they put extra info about the city next to the serps. that is all that is happening. there's nothing special about it. if a word has more than one meaning, google just measures which one gets the most clicks and sticks some extra info about it at the side.
all this talk about "second brains" is just a load of PR nonsense to try and get people talking about
