Abstract

A method is provided for ranking a plurality of items. The method comprises initializing a (D-1) dimensional weight space including a feasible region, where D is equal to a number of attributes and a point in the weight space corresponds to each attribute, determining an item pair, and querying a user to select an item from among the item pair. The method further includes reducing the feasible region based upon a user's item selection, and ranking the items according a ranking point in a reduced feasible region. The ranking point is a center of the reduced feasible region, wherein the center is one of a vertex barycenter and center of gravity. The ranking point corresponds to a users item selection. The method includes the step of selecting a plurality of hyperplanes, each hyperplane corresponding to an item pair such that the hyperplane divides the feasible region into two substantially equal portions.
