Personalized tag ranking
First Claim
1. A method for personalized tag ranking of images, the method comprising:
- identifying within a reference image collection any images that are similar to an input image in accordance with a first predefined image similarity measurement;
identifying within a source image collection any images that have associated tags that are similar to a set of input tags in accordance with a predefined tag similarity measurement, wherein said set of input tags is associated with said input image;
identifying among said images identified in said reference image collection any images that are similar to said images identified in said source image collection in accordance with a second predefined image similarity measurement;
calculating a weight for each of a plurality of tag pairs, wherein each of said tags in each of said tag pairs is associated with a different subset of said images in said reference image collection identified as being similar to said images identified in said source image collection, and wherein said weight is calculated in accordance with a predefined weight function; and
ranking said input tags of said input image in accordance with a predefined ranking function as applied to said tag pair weights.

Abstract
Personalized tag ranking of images, including identifying within a reference image collection any images that are similar to an input image, identifying within a source image collection any images that have associated tags that are similar to a set of input tags associated with the input image, identifying among the images identified in the reference image collection any images that are similar to the images identified in the source image collection, and calculating a weight for each of a plurality of tag pairs, where each of the tags in each of the tag pairs is associated with a different subset of the images in the reference image collection identified as being similar to the images identified in the source image collection, and ranking the input tags of the input image in accordance with a predefined ranking function as applied to the tag pair weights.

7. A method for personalized tag ranking of images, the method comprising:
-
identifying within a reference image collection any images that are similar to an input image in accordance with a first predefined image similarity measurement; identifying within a source image collection any images that have associated tags that are similar to a set of input tags in accordance with a predefined tag similarity measurement, wherein said set of input tags is associated with said input image; representing in a plurality of groups said images identified within said source image collection, wherein each of said groups is associated with a different tag in said set of input tags; identifying within said groups of images identified within said source image collection any images that are similar to said images identified within said reference image collection in accordance with a second predefined image similarity measurement; representing in a plurality of subsets of said groups said images within said source image collection identified as being similar to said images identified within said reference image collection, wherein each of said subsets is associated with said tag of said group of which said subset is a subset; calculating for any pair of said subsets a similarity value between said images represented by said pair of subsets in accordance with a third predefined similarity measurement, and a weight for each pair of said tags associated with said pair of subsets as a predefined function of said similarity value and a predefined function of a tag-based similarity value calculated between said pair of tags; and ranking said input tags of said input image in accordance with a predefined ranking function as applied to said tag pair weights. - View Dependent Claims (8, 9, 10, 12)
