Abstract: There are many methods of ontology-based knowledge modeling. However, there are some deficiencies in adopting traditional ontology modeling methods in some specific domain. This paper takes emergency domain ontology as an example and proposes a knowledge modeling method based on event ontology. Event ontology model is divided into upper event class, lower event class and event individuals. The upper event class describes an abstract classification system and the lower event class is an event lattice structure composed of event class relationships. This model can not only describe the time, place, objects and other elements of the event class, but also describe the relationships between the event classes. It uses the ontology modeling tool Protégé to construct the emergency domain ontology and takes the “terrorist attack” as an example to verify the usability of this model. The experimental results show that this model can describe the integrity of event class clearly, expresses semantics clearly and has strong expandability.
