Topic-Sensitive page rankings feasible

A new paper by a Stanford group claims substantial increase in calculating Page Rank performance (used by Google), which could make room for personalized topical searches.

“Computer science researchers at Stanford University have developed several new techniques that together may make it possible to calculate Web page rankings as used in the Google search engine up to five times faster. The speed-ups to Google’s method may make it realistic to calculate page rankings personalized for an individual’s interests or customized to a particular topic.” (via BoingBoing)
