Seek and He Shall Find.

The article profiles Tao Yang, professor of computer science at the University of California at Santa Barbara, California. Yang is chief scientist for Ask.com, the search engine formerly known as Ask Jeeves, which revamped its site in February 2006, dropping its butler mascot. Using the Expert-Rank search algorithm, which Yang helped develop five years ago, Ask.com identifies "expert" Web pages and uses their links to rank other sites, rather than by overall Web popularity. Yang also helped Ask.com develop the way it provides answers.
