Combining Information Sources for Video Retrieval

The previous video track results demonstrated that it is far from trivial to take advantage of multiple modalities for the video retrieval search task. For almost any query, results based on ASR transcripts have been better than any other run. This year’s main success in our runs is that a combination of ASR and visual performs better than either alone! In addition we experimented with dynamic shot models, combining topic examples, feature extraction and interactive search.
