How Google Evaluate New Search Algorithms

Few days ago Head of Search Spam Matt Cutts gives us a video that describe how Google evaluating new search algorithm which one they are going to use or which one they are going throw away.

A question was asked by James Foster of Sydney:


What metrics Google used to calculate that one function of the ranking algorithm is gives the good quality result to user than other?

Matt Cutts give the answer into the three steps, that how they evaluate search algorithms:

  1. They test the results of the algorithms and compare their results rank with the new algorithms offline, If the URLs in the result are of high quality then the last algorithms takes place. The quality of a URL is based on search quality raters that how they rate the URLs in the last cases. If the URLs are not rated, then Google could request the raters  to rate the new URLs or benchmark the previous search result to this set of new test. Based on these metrics, Google can decide to carry on to the next level.
  2. Online Tests, here Google have the sample of real live searchers and place them to the new results with the new test algorithm sets. If Google catch the high rate of clicks in new search results, then it shows that the results in this are better than older ones. Matt Cutts said that, this case is not for always but in general the more click at the specific search result page more is the quality result.
  3. After that the Search Quality Launch Committee of Google have to decide that the algorithm is going to live or not. Matt Cutts told that Google have a “very pretty system” but they need to filter some of his processes within the workflow.

Taylor Swift Unhappy After Princeton Review Misquotes Her Lyrics in SAT Test Paper

The popstar of several multi-million dollar hits and multi-million dollarlegs, Taylor Swift is not one to be messed with. The Princeton Review found that out the hard way after they published Tay Tay's lyrics as an example of bad grammar on a SAT practice test.

To be fair, they were trying to make the point that pop songs are where grammar goes to die and also cited other pop singers such as Katy Perry, Justin Timberlake, Lady Gaga and Kesha.

The fiercely loyal Tay Tay fans were not likely to let this go by and Tumblr user Nava who was apparently having ' an amazing time studying for SAT' when she spotted this, posted a snapshot with the caption, " .... it isn't a pop song it's a country pop song so take that Princeton review Taylor is grammar queen so shhhhhh.."

Unluckily for the Princeton Review however they misquoted the lyrics of the song Fifteen. The question paper wanted students to grammatically correct, "Somebody tells you they love you, …

Jessica Lange Is Definitely Done With American Horror Story But Look Who's Checking in...

Good news and bad news, American Horror Story fans.

Queen Jessica Lange confirmed at tonight's PaleyFest panel that she will not return for American Horror Story: Hotel.

"Yes, I'm done," she told the audience, "We've had a great run here. I have absolutely loved doing these four characters that I've had the opportunity to play. In all the madness, I've loved the writers, my actors, Ryan and the whole, I mean, insanity of it, shooting here, shooting in new orleans, the stories, everything."

While that is definitely not music to our ears, the panel did offer up a few happier Hotel tidbits, like the fact that White Collar star Matt Bomer will be joining the show for the season, along with 30 Rock star Cheyenne Jackson. Both Bomer and Jackson are pretty familiar with Ryan Murphy and co, having both guest starred on Glee. Bomer also appeared in American Horror Story: Freak Show as a prostitute who was brutally murdered by Dandy (Finn Witrock).

At a mere 13 millimeters thick and weighing just two pounds, it approaches the iPad’s portability and is just as spartan, sporting only a solitaryconnector.
