In this paper we describe the findings from the K-Space interactive video search experiments in TRECVid 2007, which examined the effects of including temporal context in video retrieval. The traditional approach to presenting video search results is to maximise recall by offering a user as many potentially relevant shots as possible within a limited amount of time. 'Context'-oriented systems opt to allocate a portion of the results presentation space to providing additional contextual cues about the returned results. In video retrieval these cues often include temporal information such as a shot's location within the overall video broadcast and/or its neighbouring shots. We developed two interfaces with identical retrieval functionality in order to measure the effects of such context on user performance. The first system had a 'recall-oriented' interface, where results from a query were presented as a ranked list of shots. The second was 'context-oriented', with results presented as a ranked list of broadcasts. 10 users participated in the experiments, of which 8 were novices and 2 experts. Participants completed a number of retrieval topics using both the recall-oriented and context-oriented systems.
