Abstract
A system for increasing user interaction with a digital video library. In response to receiving a question by an interactive digital video library server from a user regarding course material being presented from a digital video library, it is determined whether the question is in an audio format. In response to determining that the question is in an audio format, the question is converted into a text format. The course material is searched in a time sliced video index database for an answer to the question using keywords found in the text format of the question. Also, other course materials similar to the course material are searched in a video knowledge base. A weight is assigned to each search result hit found in the course material and the other course materials. Search result hits are outputted in a priority order according to assigned weight and user preference.
