An Iterative Data Collection Approach for Multimodal Dialogue Systems

Abstract

This paper deals with the way in which data for multimodal dialogue systems are  collected. We argue that for multimodal data, an iterative data collection strategy should be followed. Instead of a single major data collection effort using a "Wizard of OZ" (WOZ) or "prompting" experimental setup, several smaller data collections should accompany the system development. We also describe the "script" experimental setup we  developed. It is in between the WOZ and prompting setup, and can be used as a cost  effective design for the first data collection within the iterative data collection strategy.
