A Method to Transform Textual Cases into Scenario Evolution Maps

In this paper, a method to transform textual cases into scenario evolution maps is developed, and the process of developing scenario evolution map is introduced in detail. Advantages of the method lie in three aspects: clear definition and formal representation of scenarios are provided as well as the spatio-temporal framework of scenarios; scenario objects in the same object category may use a universal scenario representation which contributes to similarity assessment of different scenarios; scenario evolution map provides description of disaster evolution process in a spatiotemporal manner.
