Abstr act. In this paper we describe our experience in modeling and using sensor knowledge of a national hydrologic information system in Spain. We developed a web application called VSAIH supported by a knowledge-based system to analyze sensor data and to generate explanations that help users to make decisions based on hydrologic behavior. In the paper, we describe the characteristics of the infrastructure of hydrologic sensors and the representation we used to model sensor knowledge to provide support to the VSAIH application. We also describe semi-automatic procedures that we applied to construct the final model.

Presentation models are used by intelligent user interfaces to automatically construct adapted presentations according to particular communication goals. This paper describes the characteristics of a presentation model that was designed to automatically produce multimedia presentations about the summarized behavior of dynamic systems. The presentation model is part of the MSB application (Multimedia Summarizer of Behavior). MSB was developed for the problem of management of dynamic systems where different types of users (operators, decision-makers, other institutions, etc.) need to be informed about the evolution of the system, especially during critical situations. The paper describes the details of the presentation model based on a hierarchical planner together with graphical resources. The paper also describes an application in the field of hydrology for which the model was developed. KEYWORDSPresentation model, multimedia user interface, behavior summarization.

“…This distance is a way to quantify the degree of relevance of events. Based on our assumption for system modeling (with approximated knowledge for system behavior) the representation of relevance establishes preferences between states based on relations that summarize sets of behaviors [4].…”

Abstract. This paper describes a knowledge-based approach for summarizing and presenting the behavior of hydrologic networks. This approach has been designed for visualizing data from sensors and simulations in the context of emergencies caused by floods. It follows a solution for event summarization that exploits physical properties of the dynamic system to automatically generate summaries of relevant data. The summarized information is presented using different modes such as text, 2D graphics and 3D animations on virtual terrains. The presentation is automatically generated using a hierarchical planner with abstract presentation fragments corresponding to discourse patterns, taking into account the characteristics of the user who receives the information and constraints imposed by the communication devices (mobile phone, computer, fax, etc.). An application following this approach has been developed for a national hydrologic information infrastructure of Spain.
