Video classification boosting

Abstract

A video classification score boosting method boosts classification scores for videos for increased accuracy. A target video is classified with a classifier, producing a classification score. Related video scores are determined using the classifier for sets of videos related to the target video. The sets of related videos may include co-browsed videos, co-commented videos, co-queried videos, and co-uploaded videos. The related video scores may be the mean or median classification score for the classified sets of related videos. Weighting coefficients associated with the classifier are retrieved and applied to the classification score and the related video scores. The weighting coefficients may be determined for the classifier by classifying sets of pre-classified videos with the classifier and determining the weighting coefficients which, when applied to the classification scores of the pre-classified videos, improves the accuracy of the classification scores. A boosted classification score is determined based on the weighted classification score and related video scores.
