1. Computer-storage media storing computer-useable instructions, that, when executed by a computing device, perform a method for re-ranking images based on image annotations, the method comprising: receiving a search query for an image from a user; determining an original order of responsive images to the search query; identifying duplicate images and words associated with the duplicate images; identifying common words of the words associated with the duplicate images; annotating the responsive images with the common words; determining an annotated order of the responsive images with annotations, the annotated order being determined based on a matching score that is estimated between the search query and the annotations; determining a re-ranked order of the responsive images based on the original order and the annotated order; and presenting the responsive images to the user in the re-ranked order.

The media of claim 1 wherein determining a re-ranked order of the responsive images comprises: training a ranking mathematical model to determine a weight factor for the original order and the annotated order; applying the respective weight factor to the original order and the annotated order to determine the re-ranked order.
