David DeVault, Anton Leuski, Kenji Sagae: “An Evaluation of Alternative Strategies for Implementing Dialogue Policies Using Statistical Classification and Rules”

November 9, 2011 | Chiang Mai, Thailand

Speaker: David DeVault, Anton Leuski, Kenji Sagae
Host: The 5th International Joint Conference on Natural Language Processing (IJCNLP 2011)

We present and evaluate a set of architectures for conversational dialogue systems, exploring rule-based and statistical classification approaches. In a case study, we show that while a rule-based dialogue policy is theoretically capable of high accuracy if perfect natural language understanding (NLU) is assumed, a classification approach that combines the dialogue policy with NLU has practical advantages.
