Abstract
A method for determining a semantic concept classification for a digital video clip, comprising: receiving an audio-visual dictionary including a plurality of audio-visual grouplets, the audio-visual grouplets including visual background and foreground codewords, audio background and foreground codewords, wherein the codewords in a particular audio-visual grouplet were determined to be correlated with each other; determining reference video codeword similarity scores for a set of reference video clips; determining codeword similarity scores for the digital video clip; determining a reference video similarity score for each reference video clip representing a similarity between the digital video clip and the reference video clip responsive to the audio-visual grouplets, the codeword similarity scores and the reference video codeword similarity scores; and determining one or more semantic concept classifications using trained semantic classifiers responsive to the determined reference video similarity scores.
