This paper describes an approach to the automatic presentation of multimedia documents based on parsing and syntax-directed translation using Relational Grammars. This translation is followed by a constraint solving mechanism to create the final layout. Grammatical rules provide the mechanism for mapping from a representation of the content of a presentation to forms that specify the media objects to be realized. These realization forms include sets of spatial and temporal constraints between elements of the presentation. Individual grammars encapsulate the "look and feel" of a presentation and can be used as generators of that style. By making the grammars sensitive to the requirements of the output medium, parsing can introduce flexibility into the information realization process. Keywords: Automatic design, grammar-directed design, visual languages, relational grammars, parsing, constraints 2: Introduction A fully functioning multimedia system requires a wide range of stages to achi...

Design of information presentation is undergoing significant changes. Documents are information interfaces that must dynamically reconfigure themselves based on their content, the medium in which they are displayed, and the intended use of the information they present. Increases in computational power and the increased bandwidth of interconnected networks provide greater access to information. These factors, combined with the realization that not all of this information can now be pre-designed, necessitate new tools and techniques to ensure the effective presentation of computer-based information. This dissertation exploits the structure of information to support the design of dynamic documents. From this structure, visual languages
