Generating Visual Arguments: a Media-Independent Approach

The research reported here is part of our ongoing effort (Kerpedjiev et al. 1997b; 1997a; Green, Carenini, & Moore 1998; Green et al. 1998; Kerpedjiev et al. 1998) to design systems that can automatically generate integrated text and information graphics presentations of complex, quantitative data. In this paper, we take the position that certain types of arguments that can be presented visually in information graphics (e.g., bar charts and scatter plots) can be generated from an underlying media-independent representation of a presentation. In support of this claim, rst we brie y describe the architecture we are developing for the generation of integrated text and information graphics presentations. In this architecture, mediaindependent communicative acts are transformed into user task speci cations which are the basis for the automatic design of the presentation's graphics. Then we present an example showing correspondences between the media-independent representation of an argument and the tasks that would be used to design a graphic expressing the argument.
