Claim One:
1. A method, comprising: for a subject category of interest having a plurality N of sub-categories, where N is an integer greater than one, training over a first set of images a plurality of image classifiers to yield a plurality of pre-trained classifiers (C 1. .. C N ), where each individual one of the pre-trained classifiers is trained to recognize one sub-category of the plurality of sub-categories; obtaining a second set of images (i=1. .. M) from at least one social media website that a person has shared/posted/pinned or otherwise expressed an interest in, where M represents a total number of images in the second set of images; applying at least some of the pre-trained classifiers (C 1. .. C N ) to each image i in the second set of images; obtaining a classification score vector S i =[s 1. .. , s N ] for image i(i=1. .. M), where s j indicates a classification score output from a classifier C j by applying it to image i; aggregating the M classification score vectors over all of the images of the second set of images; and deriving a data construct that is descriptive of a preference profile of the person with respect to the sub-categories of the category of interest as a probability distribution over the N sub-categories.
