Indexing, searching, and skimming of multimedia documents containing recorded lectures and live presentations

ABSTRACT

This demonstration illustrates different ways to support users dealing with recorded live presentations in order to improve the usability of the corresponding documents. It highlights different problems in this context and presents solutions and alternative approaches for both, multimedia indexing and query processing as well as user interface issues in order to support users who are skimming or browsing such documents in search for information.
