Three video search systems were compared in the interactive search task at the TRECVID 2003 workshop: a <i>text-only</i> system, which searched video shots through transcripts; a <i>features-only</i> system, which searched video shots through 16 video content features (e.g., airplanes and people); and a <i>combined</i> system, which searched through both transcripts and content features. 36 participants each completed 12 video search tasks. The hypothesis that the combined system would perform better than both the text-only and the features-only systems was not supported, and large topic effects were found. Further analysis showed that concept-based video retrieval worked best for <i>specific</i> topics, whereas the hybrid retrieval techniques which combine both concept- and content-based video retrieval showed some advantage when searching for <i>generic</i> topics. The results have implications for topic/task analysis for video retrieval research, and also for the implementation of hybrid video retrieval systems.
