Abstract
We propose a new metric, Voted Appropriateness, which can be used to automatically evaluate dialogue policy decisions, once some wizard data has been collected. We show that this metric outperforms a previously proposed metric Weak agreement. We also present a taxonomy for dialogue model evaluation schemas, and orient our new metric within this taxonomy.

Two of the judges also performed the role of the wizards, but the wizard data collection and the evaluation tasks were separated by a period of over 3 months.
