Ontological Approaches to Modelling Narrative

We outline a simple taxonomy of approaches to modelling narrative, explain how these might be realised ontologically, and describe our continuing work to apply these techniques to the problem of Memories for Life

08091 Abstracts Collection -- Logic and Probability for Scene Interpretation

From 25.2.2008 to Friday 29.2.2008, the Dagstuhl Seminar 08091 ``Logic and Probability for Scene Interpretation\u27\u27 was held in the International Conference and Research Center (IBFI), Schloss Dagstuhl. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put together in this paper

Generating Presentation Constraints from Rhetorical Structure

Hypermedia structured in terms of the higher-level intent of its author can be adapted to a wider variety of final presentations. Many multimedia systems encode such high-level intent as constraints on either time, spatial layout or navigation. Once specified, these constraints are translated into specific presentations whose timelines, screen displays and navigational structure satisfy these constraints. This ensures that the desired spatial, temporal and navigation properties are maintained no matter how the presentation is adapted to varying circumstances. Rhetorical structure defines author intent at a still higher level. Authoring at this level requires that rhetorics can be translated to final presentations that properly reflect them. This paper explores how rhetorical structure can be translated into constraints, which are then translated into final presentations. This enables authoring in terms of rhetorics and provides the assurance that the rhetorics will remain properly conveyed in all presentation adaptation

LAYLAB : a constraint-based layout manager for multimedia presentations

When developing advanced intelligent user interfaces composing text, graphics, animation, hypermedia etc., the question of automatically designing the graphical layout of such multimedia presentations in an appropriate format plays a crucial role. This paper introduces the task, the functionality and the architecture of the constraint-based multimedia layout manager LayLab

Flexible and scalable digital library search

In this report the development of a specialised search engine for a digital library is described. The proposed system architecture consists of three levels: the conceptual, the logical and the physical level. The conceptual level schema enables by its exposure of a domain specific schema semantically rich conceptual search. The logical level provides a description language to achieve a high degree of flexibility for multimedia retrieval. The physical level takes care of scalable and efficient persistent data storage. The role, played by each level, changes during the various stages of a search engine's lifecycle: (1) modeling the index, (2) populating and maintaining the index and (3) querying the index. The integration of all this functionality allows the combination of both conceptual and content-based querying in the query stage. A search engine for the Australian Open tennis tournament website is used as a running example, which shows the power of the complete architecture and its various component

Perspektiven zur Kombination von automatischem Animationsdesign und planbasierter Hilfe

Aktuelle Themen auf dem Gebiet der intelligenten Benutzerschnittstellen behandeln derzeit die automatische Planung multimodaler Präsentationen. Hierbei stand bisher im wesentlichen die koordinierte Generierung von Text und Graphik im Vordergrund. In Zukunft wird hier aufgrund der Komplexität der zu präsentierenden Information zunehmend auch die Einbeziehung realistischer animierter 3D-Graphiken gefordert sein. Einen anderen wichtigen Forschungsschwerpunkt bildet der Einsatz graphischer Ausgabekomponenten für planbasierte Hilfesysteme. Die vorliegende Arbeit hat zum Ziel zunächst einen Überblick über den derzeitigen Stand der Forschung in diesen beiden Bereichen zu geben, als auch neue Anforderungen an die automatische Animationsgenerierung und an Systeme zur planbasierten graphischen Hilfe zu formulieren. Anschließend wollen wir, basierend auf Ergebnissen und Erfahrungen aus WIP und PLUS, Perspektiven für eine mögliche Weiterentwicklung und Integration von Techniken der Animationsplanung und graphischen Hilfe präsentieren
