In this paper, we propose a framework of supporting presentation scenario composition from a viewpoint of externalizing a presenter's intention. Traditional presentation slides in the style of bullet lists lack in rhetorical relation between idea fragments. This makes it difficult that audiences could successfully understand presentation utterances and presentation slides. In order to solve this problem, we introduce a concept of logical frame. The logical frame is a semantic block in which idea fragments are organized rhetorically. A presentation scenario is composed through the process of producing idea fragments within a logical frame and relating logical frames to each other. Based on this model of presentation scenario, we have implemented a scenario composition interface.
