More and more presentation contents, which consist of heterogeneous media such as videos and slides, have recently been recorded and viewed. In e-Learning, we often use presentation contents archives. However, if there is a slide that includes a keyword that the users do not know, it is difficult for them to understand the rest of the presentation contents. So, they must stop viewing it and look up the keyword. In this paper, we propose an interval-retrieving method that is based on the user’s viewing operations. By using this method, we extract the user’s interval-retrieving intention using his/her viewing operations and selected keywords. Queries are also generated for the intervals by using the user’s retrieving intention and a keyword role in the intervals. This method also enables the users to obtain intervals that help them to more efficiently understand the contents of the presentation without discontinuing viewing them.
