Evaluating dialog systems used in the real world
Harald Aust, Hermann Ney · 2002
An important aspect of creating high performance natural language dialog systems is the question of how they are evaluated. While a universally accepted method for doing so for pure speech recognition exists, this is not clear for speech understanding or dialog systems. We describe the methods we typically use for our systems and argue that it is not sufficient to evaluate their constituents separately. Instead, a measure for a system in its entity is needed.
