SOFERS: Scenario Ontology for Emergency Response System

with the ability to assist people to make reasonable decisions in an emergency, scenario-response paradigm has been widely regarded as one of the most effective emergency management models. In order to promote the processing capacity of scenario information for Emergency Response System (ERS), a new kind of scenario ontology is proposed in this paper. Following the wellknown modeling primitives, the scenario ontology is constructed on the basis of PROTON (Proto Ontology), the reference layer ontology of FactForge that includes some central datasets of Linked Open Data (LOD). The event module, scenario module and mitigation module comprise the core level scenario ontology, defined with some core concepts and relations, which can be reused in the domain level scenario ontology. Considering earthquake is a representative emergency, we analyze the scenario information required by decision makers in some earthquakes, and design the scenario ontology of earthquake as an example in the domain level scenario ontologies. To show the validity of the scenario ontology, we implement the scenario ontology of earthquake with Protégé and develop a prototype system, which can retrieve some parts of scenario information from FactForge and provide a visualization interface for decision makers to browse the scenario instances involved in an earthquake.
