Application ID: 13375565

Base Claim:
1. A computer-implemented method, comprising: obtaining a reference text label that specifies a first topic to which a reference image is relevant; identifying, in a data processing system and as a co-selected image for the reference image, an image that was presented in image search results and selected by a user during a same user session in which the reference image was presented in the image search results and selected by the user; generating, in the data processing system, a topic score for the co-selected image based on a number of user sessions in which image search results included both the co-selected image and the reference image and in which a user interacted with both of the reference image and the co-selected image, the topic score representing a measure of relevance of the co-selected image to the first topic; and labeling the co-selected image as an image that is relevant to the first topic based on the topic score meeting a threshold topic score.

Claim 13:
13. The method of claim 1 , wherein generating a topic score comprises: obtaining initial topic scores for the co-selected image, each initial topic score being an initial relevance measure of the image to the first topic; obtaining co-selection data for the co-selected image, the co-selection data specifying selections of the co-selected image relative to selections of the reference image; computing an updated topic score for the co-selected image based on a function of the initial topic scores and the co-selection data; determining whether a stop condition has occurred; when the stop condition has not occurred, computing additional updated topic scores based on the co-selection data and previously computed updated topic scores; when the stop condition has occurred, classifying the co-selected image based on the updated topic scores; and wherein the labeling is based on the updated topic scores.
