Abstract: Relevance is one of the most fundamental concepts in information science. However, very little research has studied users' relevance judgments concerning video. The study conducted exploratory work in this direction through a semi-structured interviewing of participants who were video editors/producers, university professors who use videos in classroom, and video librarians. Three categories of relevance judgment criteria were summarized: textual, visual and implicit. Topicality was still considered the most important criteria for video relevance judgments; however, users also liked to see visual surrogates, especially those that contained motion. It is expected that the results will not only enrich the relevance literature but also have implications for video indexing and retrieval research.
