ROBUST 2004 Research Workshop on Robustness Issues in Conversational Interaction, University of East Anglia, Norwich, UK, August 30-31, 2004An important tradeoff in error-prone dialogue is between
the cost of using more robust dialogue strategies and the
cost of recovering from failed understanding without using
them. A strategy has to be quantitatively planned for each
dialogue state, since too robust a strategy might not have a
worthwhile effect on the failure rate. A dialogue manager is
described which chooses between strategies that have
differing levels of robustness with a view to maximising the
efficiency of the dialoguekpw1/8/1
