    Abstract

    Contemporary video retrieval systems are wanting in terms of helping users find appropriate videos. There are a number of reasons for this, including a lack of appropriate representations for video and the semantic gap. These problems are amplified by the fact that the importance of expertise for effective video search is not well understood. In an attempt to garner a greater understanding of the impact of expertise on video search, a user evaluation that is designed to investigate the role of expertise in video search was conducted. In our evaluation participants were given a number of video search tasks and were asked to find relevant videos using two different interfaces: the first interface required users to use background knowledge to find relevant videos and the second interface allowed users to use video search tools to complete the task.
