Abstract:
1. A method performed by a data processing apparatus, the method comprising: accessing, by the data processing apparatus, images stored in an image data store, the images being associated with respective sets of labels, the labels describing content depicted in the image and having a respective confidence score that is a measure of confidence that the label accurately describes the content depicted in the image; accessing, by the data processing apparatus, one or more proximity metric values associated with the images; selecting, by the data processing apparatus, a first image from the accessed images; determining, for each of the other images of the images, a proximity score based on a comparison of the proximity metric values of the first image and corresponding proximity metric values of the other image, the proximity score being a measure of a relatedness of the other image to the first image, and wherein each proximity score is determined independent of the labels of the images; and adjusting, by the data processing apparatus, a confidence score associated with a particular label associated with the selected first image based on the respective proximity scores of the other images that each include a label that corresponds to the particular label and the confidence scores of the corresponding labels of the other images.
