The folks at google have crunched the numbers relating to historical search data and the Oscar’s. And, what they have found could shed some light on, or even predict, the Oscar winners this weekend.

The Google search team broke down the search data on three Oscar’s categories: Best Picture, Best Actor, and Best Actress. Based on their data, they have some prognostications.

From the Google Blog:

Best Picture
Last year we found that for three years running, the films that won best picture had two things in common when it came to search data. First, the winning movies had all shown an upward trend in search volume for at least four consecutive weeks during the previous year. Second, within the U.S. the winning film had the highest percentage of its searches originating from the state of New York. Looking at search data for 2011, there were three films that satisfied these conditions—The King’s Speech, The Social Network and Black Swan. Our prediction was on the mark: The King’s Speech took home the Oscar in 2011.

This year, if we assume the two “winning conditions”—at least four consecutive weeks of increasing search volume plus highest regional interest from New York—will apply, then we can narrow down the nominees to a field of four: The Artist, Extremely Loud & Incredibly Close, Midnight in Paris and War Horse. But how to go from four to one?

Let’s again look back at last year’s finalists. When you compare search query volumes for The King’s Speech, The Social Network and Black Swan, the winning film, The King’s Speech, had the lowest search volume throughout the year leading up to the Oscars. It was the underdog that took home the statue.

We tried the same test on the Best Picture nominees from 2010. The nominated movies in 2010 that met the two conditions were The Hurt Locker and Inglourious Basterds. Once again, it was the the winning film, The Hurt Locker, that had lower search volume in 2009.

If the underdog trend holds this year, Extremely Loud & Incredibly Close could be our surprise winner. If we go strictly by search popularity, however, The Artist or Midnight in Paris have the best chances—among our group of four, they’re currently blowing the competition out of the water.

Best Actor
Of this year’s five nominees for Best Actor, Brad Pitt (Moneyball) is clearly the most popular—searches for Brad in the last 12 months far outpace any of the other leading men, as was the case in 2009 when he was nominated for The Curious Case of Benjamin Button. However, it could be Brad’s famous good looks that have us searching, which brings about a good point: the most searched-for nominee doesn’t guarantee a win. James Franco had the highest search volume in 2011 but Colin Firth won, and in 2010, George Clooney was the most-searched nominee but Jeff Bridges took home the Oscar.

The pattern emerging over the past few years is that the winner is generally in the middle of the pack in terms of searches and has relatively steady search volume throughout the year. First-time nominee Gary Oldman (Tinker Tailor Soldier Spy) fits that bill this year, but so does George Clooney (The Descendants). Maybe it will finally be George’s year to win Best Actor.

Best Actress
For the past three years, the eventual Best Actress winner has seen a spike of interest in the preceding December. Additionally, two of the three most recent winners have had the strongest regional interest within the U.S. from the cities of Los Angeles and New York City (2010 winner Sandra Bullock is the exception).

Among this year’s nominees, Rooney Mara is the clear breakout star, with a huge surge in search volume this past December for the young lead in The Girl with the Dragon Tattoo. However, it’s Meryl Streep who has the highest regional interest in NYC and while Rooney is popular in LA, she’s even more popular in San Francisco. So it could be her name that is announced when the envelope is opened—or not.
