An Interval Ranking Method of Multimedia Presentation based on Relative Query Keyword Position

Presentation content can consist of heterogeneous media, such as videos and slides, which have been recorded and used. A variety of retrieval methods have been proposed for each kind of stored media. This paper proposes an extraction method using the features of each type of media. The proposed method specifically uses presentation video and slides. A user inputs query keywords, which are used to extract the most appropriate interval for the query according to appearance positions in the media. This enables the user to extract intervals that can be viewed more efficiently than when the interval depends only on the presence of query keywords.
