FXPAL Interactive Search Experiments for TRECVID 2007

We submitted six interactive search runs for TRECVID2007, including 2 single user and 4 collaborative runs. In one single-user run (FXPAL MMA) the searchers had access to all resources including text search, text similarity, image similarity, and concept similarity search. In the other single-user submission (FXPAL MMV) the transcripts were not available and only features derived directly from the audio-visual content were available. This is a typical baseline for the manual and automatic search systems, but has been a less popular variation among the interactive search submissions. The other submitted runs (FXPAL CO*) employed a novel real-time, multi-user, collaborative search system.
