摘要

The present invention is a method and system for learning models of the preferences of members drawn from some population or group, utilizing arbitrary paired preferences of those members, in any commonly used ranking model. In particular the present invention involves techniques for learning Mallows models, and mixtures thereof, from pairwise preference data.

1. A computer implemented method of identifying and ranking preferences regarding a plurality of options, for a group including two or more members, the method comprising:
(a) obtaining from one or more data sources, preference information, including partial preference information, for the members, or a subset of the members, wherein the partial preference information may include a set of pairwise comparisons involving one or more of the options; (b) analyzing, by operation of one or more server computers, the pairwise comparisons so as to learn one or more statistical models for inferring and ranking a set of preferences based on the partial preference information; and (c) applying the one or more statistical models so as to identify the set of preferences and rank the options.
