SEMI-AUTOMATED ANNOTATION AND RETRIEVAL OF DANCE MEDIA OBJECTS

Abstract

This article considers a system for the semiautomatic annotation of an audio-visual media of dance domain, DMAR (Dance Media Annotation, authoring and Retrieval system). We present the architecture of the system, a manual annotation tool, a semiautomatic authoring tool and a search engine for the choreographers, dancers and students to demonstrate how the dance media can be semantically annotated and how this information can be used for the retrieval of the dance media objects. This article then outlines the underlying XML Schema based content description structures of DMAR and discusses the merits and demerits of our approach of evolving semantic network as the basis for the audio-visual content description. Further, this article proposes a quality metric, fidelity to evaluate the expressive power of the dance annotations. Finally, evaluation results are presented to depict the performance of the dance video queries in terms of precision and recall.
