Context aware guidance for multimedia authoring: harmonizing domain and discourse knowledge

This paper presents an approach to assist authors during the authoring of multimedia presentations. We extend the existing authoring support by integrating processes of topic identification, content collection and discourse structure building in a single environment. This integration allows identification of the context of the authoring process. Our approach combines this process context awareness with explicit domain and discourse knowledge to steer system suggestions. We evaluate our approach with an experimental system prototype.

SampLe: towards a framework for system-supported multimedia authoring

Multimedia authoring is a complex, resource demanding, knowledge-intensive, and multilayered process. While a large part of presentation creation cases involve manual production of presentations, such as performed in daily work of students and teachers, most applications for manual production (e.g. PowerPoint, Director) are only working environments with no help on the conceptual level. We propose a framework for the authoring system called SampLe (semiautomatic presentation generation environment), where the system support is provided at any stage of the presentation building process. The support is managed by incorporating explicit knowledge about the domain, narrative structures, media modalities, and tasks involved into the process of multimedia presentation creation.

Combining coherence and adaptation in discourse-oriented hypermedia generation

This paper provides a solution to discourse structure adaptation in the process of automatic hypermedia presentation generation. Existing approaches to discourse structure composition are based on the assumption that a user can comprehend relations between the elements in a discourse structure if the overall structure is semantically coherent. This assumption does not, so far, take into account specific user needs. In this paper we show that although discourse structure composition approaches significantly differ, a general model of the composition process can be derived. Within this general model we identify how adaptation can be applied. We formulate the problem of discourse adaptation with regard to the general model and present our proposed solution.
