民話風物語生成・表現システムKOSERUBE第一版の開発

抄録

KOSERUBE (version 1) is a system that automatically generates stories and discourses in the style of a folk tale with its characters, places and objects relating to Iwate Prefecture. The system also expresses sentences and music, and automatically edits visual objects relating to the generated narratives. The user can operate and appreciate the process through a visual interface. In the context of our narrative generation system research, KOSERUBE mainly uses Propp-based story grammar as the major automatic generation mechanism. In this paper, first, we give a system overview covering the user interface and the narrative generation mechanism depending on Propp-based story grammar. Next, we present the results of a questionnaire survey and a demonstration at an exhibition to identify relevant issues and discuss the expansion of the system to the second version. One of the important issues identified is the processing of the narratives for consistency and naturalness. In the questionnaire survey results, both positive and negative opinions about jumps or gaps in a narrative appeared. For the development of version 2, our aim is to implement both mechanisms for managing narrative consistency and those for deviating from it. We also discuss other topics regarding the next version. Overall, we propose a new type of multimedia content system with an automatic narrative generation system.
