Abstract: High level metadata provides a way to manage, organize and retrieve multimedia data based on the actual content using content descriptions. The MPEG-7 Semantic Description Scheme provides tools for storing expressive and interpretable high level metadata. As it is currently impossible for computers to create high level metadata autonomously, users have to create the annotations manually. Generally the manual annotation of multimedia content is understood as laborious and complex task. Within this publication we assess the complexity of the annotation task for the MPEG-7 Semantic Description Scheme within a small user evaluation and the results of the evaluation are discussed.

Keywords: MPEG-7, annotation, evaluation, metadata, semantic gap
