Affordable access to multimedia by exploiting collateral data

Abstract

In addition to multimedia collections and their metadata, there often is a variety of collateral data sources available on (parts of) a collection. Collateral data - secondary information objects that relate to the primary multimedia documents - can be very useful in the process of automated generation of annotations for multimedia archives in that they reduce both costs and effort in annotation and access. Furthermore, they can be used to enhance result presentation in retrieval engines. To optimally exploit collateral data, methods for automatic indexing as well as changes in the current archiving workflow are proposed.
