【 摘 要 】

Scenarios are narratives that illustrate future possibilities or existing systems, andhelp policy makers and system designers choose among alternative courses of action. Scenario-based decision-making crosses many domains and multiple perspectives. Domain-specictechniques for encoding, simulating, and manipulating scenarios exist, however there is nogeneral-purpose scenario representation capable of supporting the wide spectrum of formalityfrom executable simulation programs to free-form text to streaming media descriptions.The claim of this research is that there is a computer readable scenario framework that cancapture the semantics of a problem domain and make scenarios an active part of decisionmaking. The challenge is to define a representation for scenarios that supports a wide range of discussion and comprehension activities while remaining independent of content and access mechanisms. This dissertation describes a scenario ontology derived by examining alternateforms of narrative: thought experiments, mental models, case-based reasoning, use cases,design patterns, screenwriting, film-editing, intelligent agents, and other narrative domains.The scenario conceptual model was based on an analysis of forms of narrative and the activities of storytelling. This method separates what a narrative is from how it is used. The research contribution is the development of the hyperscenario framework. A hyperscenariois a scenario representation containing link structures for navigation between scenario elements. The hyperscenario framework consists of the scenario ontology, scenario grammar,and a scenario specification called Scenario Markup Language (SCML). The results of theweb-enabled simulation experiment validate the improvement on decision-making due to thehyperscenario framework.
