A Semi-automated Evaluation Metric for Dialogue Model Coherence

Sudeep Gandhe, David R. Traum

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.
