1. A system, comprising: a data sampling and labeling component configured to sample training webpages having images to create positive webpage samples and negative webpage samples based on user image clicks; a feature generation component configured to employ the user image clicks to extract features from the training webpages; a model creation component configured to create a selection model for an image webpage index based on the sampled training webpages and the features, wherein the data sampling and labeling component is configured to sample the training webpages within a specified time window, and past user image clicks are used as features to train the selection model; a validation component configured to evaluate and validate the selection model for the image webpage index using benchmark data to obtain an optimal selection model; a prediction component configured to predict an image webpage static rank of newly-discovered image webpages based on the optimal selection model; and a microprocessor that executes computer-executable instructions associated with the data sampling and labeling component, feature generation component, model creation component, validation component, and prediction component.
