The subject matter of this specification can be embodied in, among other things, a method that includes determining a score for an image of a plurality of images with respect to each of one or more terms, identifying one or more of the terms for each of which the score for the image with respect to the respective identified term satisfies a criterion, and associating the identified terms with the image. Determining the score for the image with respect to a respective term includes determining probabilities of navigating between images in the plurality of images and determining the score for the image with respect to the respective term based on the probabilities.
