Quantitative scenario construction of typical disasters driven by ontology data

Abstract

This study introduces a quantitative scenario-building method for analyzing emergency scenarios based on ontological methods and the EOC (element-object-consequence) model. The ontological structure of disasters concisely describes the knowledge, concepts, attributes, and relationships of the disaster scenario. It reduces the granularity of the data from the document to the data level. Disaster ontologies comprise a set of basic knowledge of a given domain, which is reusable, relatively fixed, and applicable in different areas at different periods. The EOC model is based on the ontology of a disaster and adopts a multiclass structure for the development of a complete process scenario and the adaptation of a disaster scenario by combining objects, elements, environments, and consequences.
