Google's man behind the curtain | Newsmakers | CNET News.com

Google's man behind the curtain | Newsmakers | CNET News.com: Some computer scientists suspect that PageRank is dead, because Internet marketers have managed to exploit it by creating false popularity for their sites. Is that true? Has it been altered, or is it playing less of a role?
The point of view that PageRank is dead is kind of a very static view of the world. It will always continue to be a part of our ranking scheme but, over time, as we develop new ideas on how to do ranking, as we tweak existing ideas, as we think about new ways to have them play together--the role of any one of the techniques that we use will obviously change.

Are there any other algorithm techniques that you are using that are playing a bigger role?
Well, there are certainly other techniques that we are using. Talking about it is the trickier part. In broad terms, techniques we use fall into, like, two or three categories, and one is we try to understand and leverage human intelligence. We look for signals that people put in to indicate intelligence, like deciding to link from one page to another or annotating text with the description of what the text is about.
