ExploratoryVideoSearch: A Music Video Search System Based on Coordinate Terms and Diversification

Many people search and watch music videos on video sharing websites. Although a vast variety of videos are uploaded, current search systems on video sharing websites allow users to search a limited range of music videos for an input query. Especially when a user does not have enough knowledge of a query, the problem gets worse because the user cannot customize the range by changing the query or adding some keywords to the original query. In this paper, we propose a music video search system, called ExploratoryVideoSearch, that is coordinate term aware and diversity aware. Our system focuses on artist name queries to search videos on YouTube and has two novel functions: (1) given an artist name query, the system shows a search result for the artist as well as those for its coordinate terms, and (2) the system diversifies search results for the query and its coordinate terms, and allows users to interactively change the diversity level. Coordinate terms are obtained by utilizing the Million Song Dataset and Wikipedia, while search results are diversified based on tags attached to YouTube music videos. ExploratoryVideoSearch enables users to search a wide variety of music videos without requiring deep knowledge about a query.
