ADiEU: Toward Domain-Based Evaluation of Spoken Dialog Systems

We propose a new approach toward evaluation of spoken dialog systems. The novelty of our method is based on utilization of domain-specific knowledge combined with the deterministic measurement of dialog system performance on a set of individual tasks within the domain. The proposed methodology thus attempts to answer questions such as: "How well is my dialog system performing on a specific domain?", "How much has my dialog system improved since the previous version?", "How much is my dialog system better/worse than other dialog systems performing on that domain?"
