Abstract
Prior studies have demonstrated that embodied conversational agents, which provide opportunities to simulate realistic daily conversation situations, could be effective in motivating second language learners to communicate in the target language. However, implementing such systems in various situations requires significant knowledge-engineering effort, which limits their widespread adoption and deployment. In this paper, we present a conceptual framework for dialogue scenario design based on an ontological model of service process. We provide an overview of a scenario authoring workflow and reduced number of activities that should be conducted by scenario designers to specify both the properties of the dialogue task structure and dialogue flow logic in the targeted conversation situation. We also discuss the benefits of embedding such a common service task structure in terms of reducing the authoring load of dialogue scenarios in various task-oriented service situations.
