Abstract: Widespread crises require the deployment of a crisis team, to coordinate the disaster assistance. Because of their low frequency of occurrence and the extensive assignment of volunteers, often only less practical knowledge in managing widespread crises are available on demand. If such a crisis occurs, the gained knowledge must be quickly shared within the team. Current crisis management systems are designed to manage big amounts of situation facts, crisis teams based their work on. But very often these systems are not able to manage information about the linkage of these facts causing the problems. KIS is the first prototype of a crisis team information system, able to combine an ontology based data model for situation representation with the ability to forecast causal chained and spatially related problems derived on situation facts. KIS is able to store and manage this knowledge so that it can easily be shared with others.
