ISRST: An Interest Based Storytelling Model Using Rhetorical Relations

Abstract

Abstract. Most storytelling model approaches consider stories formed by sequences of a particular type of event. These sequences are mostly constructed using the inherent temporal characteristic of each linked event and this limitation makes it difficult to adapt the models to other kinds of events. In order to develop a more generic model to create storytelling applications, we need to organize events using not only temporal relations, but also relations determined by the rhetorical context of those events. In this paper, we present ISRST, our proposal for a generic storytelling ontology model based on the organization of events using a subset of relations proposed by the Rhetorical Structure Theory and how narrative principles and user interest are applied to these relations to generate coherent stories.

Conceptual Model and System for Genre-Focused Interactive Storytelling

“…Few efforts dedicate enough attention to relations between events. Three relevant exceptions are [15], [11], and [14]. Pinhanez [15] deals with a temporal model of events, providing mechanisms to handle their interlacing temporal relations.…”

“…The Joseph system is (to our knowledge) the first system constructed from an explicit, formal model for stories. ISRST argues that relations determined by the rhetorical context of events is key [14] and introduce an ontology model based on the organization of events. In ISRST, a relation is a binding between two entities, which refers to a specific rhetorical function.…”

“…In ISRST, a relation is a binding between two entities, which refers to a specific rhetorical function. They further claim that "its use is impractical for the purpose of content creation, since most human beings make use of a more limited set of relations to construct and remember stories" [14]. To match this limitation, a reduced set of nine relations is considered.…”

Towards a generic framework for situated collaborative storytelling

“…However, other researchers [19] point to the flexibility of rhetorical relations to connect narrative events. This allows not only the semantic relation of the text, but also the broader sense of ideas and concepts related to the text.…”

“…Combining aspects of our inherent narrative intelligence and the mental models we form around stories, this framework is be flexible enough to incorporate a large domain of existing narrative templates containing sets of semantic and rhetorical relationships. This combines CT entailment structures and the Rhetorical Structure Theory (RST) ontology model as developed by Nakasone and Ishizuka [19], where each template is mapped into Pask's cognitive distinction of declarative and procedural knowledge. The entailment nets are activated as collections of themes that contribute to the narrative in question (why), while the rhetorical relations form the procedural or possible sequences of events that can take place (how).…”
