Abstract

We present the architecture of DiaWoZ, a system supporting the design and execu- tion of Wizard-of-Oz experiments to collect data from tutorial dialogues. The architecture is highly modular and allows for the progressive refinement of the experiments by both design- ing increasingly sophisticated dialogues and successively replacing simulated components of the tutoring system by actual implementations. The dialogues to be examined are specified in a language that combines finite-state approaches with information states, thereby allow- ing for great flexibility. Therefore, the architecture should also be appropriate for examining dialogues in general.
