Abstract

The tremendous amount of data resulting from the regular usage of tools for automatic presentation recording demand for elaborate search functionality. A detailed analysis of the according multimedia documents is required to allow search at a very detailed level. Unfortunately, the produced data differs significantly from traditional documents. In this demo, we discuss the problems appearing in the presentation retrieval scenario and introduce aofSE, a search engine to study and illustrate these problems as well as to develop and present according solutions and new approaches for this task.
