Abstract
Dance video is one of the important types of narrative videos with an interesting and semantics-rich content. Modeling the expressive dance semantics is a real challenging task, compared to the other types of videos such as news, sports and video streams. This paper proposes a formal conceptual model based on the theory of regular tree automata called, DanceGrammar. The DanceGrammar and its tree automaton represent the dance pieces that are associated with the accompanying song. A dance piece incorporates many dance video semantics such as dancer objects, actors, dance movements, emotions and spatio-temporal relationships among the dancers and their actors. This paper then outlines the translation rules to convert the tree automaton of the Dance- Grammar into W3C XML Schema and presents the underlying XML Schema representations.
