Storytelling applications are increasingly being used and researched due to the fact that they are capable of conveying information and experience to users in a more natural and familiar way for them. The range of developed applications increases as we realize new ways to present content as stories or "sequences of narrative significant events". Nevertheless, implemented storytelling models are usually constrained to a particular application because of the nature of the narrated events and the way those events are linked. In order to develop a more generic model to create storytelling applications, we need to focus the solution on the manner the content is organized and conveyed to the user. We present our proposal for a generic storytelling ontology model based on the organization of events using the relations proposed by the Rhetorical Structure Theory (RST) and how narrative principles are applied to these RST relations to generate coherent stories. © 2006 IEEE.
