Roxane Segers, Tommaso Caselli, Piek T. J. M. Vossen · 2017
In this paper we describe the ongoing work on the Circumstantial Event Ontology (CEO), a newly developed ontology for calamity events that models semantic circumstantial relations between event classes, where we define circumstantial as explicit and implicit causal relations.The circumstantial relations are defined manually in the ontology for classes of events that involve a change to the same property of a participant.We discuss and contrast two types of circumstantial relations: semantic and episodic circumstantial relations.Further, we describe the metamodel and the current contents of the ontology and outline the future evaluation of the CEO.
