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.

Watch out WhatsApp: Google may be launching a free messaging app very soon

Software giant Google Inc plans to launch a mobile messaging app it is likely to test in India and other emerging markets, the Economic Times reported on Friday, citing sources.

If launched, the mobile app will compete in the mobile chat space with the likes of WhatsApp, Line and Hike.

The daily said Google was in the early stages of development of the app, which will not make it mandatory to use a Google login. Moreover, unlike WhatsApp, where users have to pay Rs 53 annually after one year of usage, Google's messaging app will be free.

Assassin’s Creed Unity: Time Anomaly Trailer Sheds New Light on Contemporary Subplot

Earlier this week, Ubisoft quietly dropped another new trailer for Assassin’s Creed Unity. The Time Anomaly trailer gave players their first hint at the contemporary storyline that will carry over into the game. In the previous games, Desmond Miles was plugged into the Animus, which detected the “genetic memories” of his ancestors. Desmond Miles is out of the picture, so the main franchise story will likely move in the direction of another character’s bloodline. The previous games featured the ancestors of Desmond Miles, and Arno Dorian is not Desmond’s ancestor. The brand new trailer offers the first look at the present-day timeline. It appears that the stakes of using the Animus have changed. The Time Anomaly trailer offers some exciting new wrinkles for the Assassin’s Creed unity storyline.
The voice of an unknown female character warns an unnamed Assassin that the French Revolution simulation is collapsing. The Assassin is likely the main player or character and the descendant of A…
