A Hierarchical Visualization Program for Computer-Generated Narratives

Automatic content generation has been receiving increasing attention recently and studies of narrative generation system have a great potential in this area. In this paper, we propose a new approach toward applications of narrative generation system. In our design concept for narrative generation systems, system's role is to produce diverse narratives and the user searches valuable narratives from the products based on one's own values. Based on this conception, we propose a visualization program for a lot of computer-generated narratives. We use a narrative discourse generation system as the narrative generation program. The visualization program hierarchically organizes and visualizes a lot of generated narratives into a two-dimensional space based on their structural feature values. The user can intuitively understand the similarity and difference among narratives. In addition, the visualization functions as a user interface for accessing and searching generated narratives. Through showing visualization examples, we discuss utilities of generated and visualized narrative contents. Especially, we focus on an application potential for support of narrative creation by people.
