The Planning Paradigm Required for Automated Multimedia Presentation Planning

Eduard Hovy, Yigal Arens

In this paper we argue that the planning of multimedia presentations requires at least two distinct (though interrelated) independent reactive planning processes: one to plan the underlying discourse structure (that is, to order and interrelate the information to be presented) and the other to allocate the media (that is, to delimit the portions to be displayed by each individual medium). The former process has been the topic of several studies in the area of automated text planning, in which the traditional methods of constructing tree-like plans in deliberative, top-down, planning mode have been applied with varying amounts of success. The latter process remains less clear, in part (we believe) because the deliberative planning mode is even less appropriate for it. We outline in this paper the reasoning behind our belief that neither planning process can be a simple deliberative top-down one and describe the kind of interplay between the two processes.
