Evaluating the Contents Generated by an Automatic Narrative Generation Game

抄録

This paper reports on the extension of an automatic narrative generation game developed by the authors in a previous study. The first extension is aimed at expanding the knowledge bases, and the second extension is focused on evaluating the generation result. The automatic narrative generation game consists of a mechanism that prepares the framework of the story and another mechanism that generates fragmentary stories. The game generates stories by inserting fragmentary stories in the framework. In this study, we attempted to generate a story using existing novel and folk tale texts as the knowledge for story generation. During the generation, we employed a quantitative evaluation using Doc2Vec’s method and considered a method of generating a story that is not as similar as possible to the original story. Furthermore, the generation results are evaluated via a method that refers to a generative adversarial network, and natural stories and unnatural stories are generated.
