Several research efforts have explored the use of dialogue act tagging schemes for tasks such as improving recognition performance (Reithinger and Maier, 1995;Shriberg et al., 2000), identifying important parts of a dialogue (Finke et al., 1998), and as a constraint on nominal expression generation (Jordan, 2000).
we decided to explore the application of a dialogue act tagging scheme to the task of evaluating and comparing dialogue systems.
