Abstract
In a general sense, stories are defined as unique sequences of events, mental states, or happenings involving human beings as characters or actors. Any properly constructed story always aims to deliver a particular message to its audience, and the content of this message is commonly conveyed through discrete pieces of information, referred to as events, so that users can assimilate the story in a more convenient and orderly way. Nevertheless, a story is not only defined by its content, but also by the manner this content is presented. Even though the information that defines the content of a story can be fixed, several different “told stories” may arise depending on how such information is sequenced. Storytelling is, in other words, the process by which content is conveyed to the audience in order to maximize not only its attention, but also its understanding and eagerness, and researchers have created extremely complex applications to enhance not only the manner a story can be told, but also the manner users can enforce their preferences in content presentation through interaction. In this context, interactive storytelling (IS) models, either implicitly or explicitly, have had to deal with three major aspects in their implementations, regardless of their technology: (1) how to define events, i.e. the pieces of information that constitutes the content of any story, (2) how to present events, i.e. the algorithm that is used to convey this content to the user, and (3) how the user is to interact with the story, i.e. the variables that the user can modify in order to change the presentation of the events in content or in order. The majority of IS implementations encode in their definition of story event timing information (the range of time specified in terms of the story timeline in which the event must be presented) and interaction variables associated with that predefined timing. This approach is convenient for story presentation, but presents several restrictions in terms of story understanding if events are not adequately organized, and story dynamism since it leaves story algorithms with little or no manipulation ability to arrange the events taking into consideration the narrative appeal to the user. In this thesis, I present ISRST (Interactive Storytelling Model using RST), my proposal for a storytelling model based on the organization of generally defined events using a subset of rhetorical relations proposed by the Rhetorical Structure Theory (RST) and the application of narrative principles and user interaction through interest to generate appealing stories.
