Abstract
In order to streamline and strengthen the knowledge acquisition process from experience feedback (accident scenarios in transport), it is necessary to harmonize and standardize the terminology used by experts and actors in the security domain. Despite all the efforts to propose approaches and techniques to manage experience feedback, most of the approaches suggested in the literature suffer from the lack of acceptable definitions and from ambiguity due to the lack or even the absence of formalism to express or model the accident scenarios. In order to build an accessible and usable knowledge model and thus provide assistance to domain experts in their crucial task of analyzing and improving security, this paper presents a generic semantic model for the representation of accident scenarios in the field of transport, based on ontologies.
