Dialog Navigator : A Spoken Dialog Q-A System based on Large Text Knowledge Base

This paper describes a spoken dialog QA system as a substitution for call centers. The system is capable of making dialogs for both fixing speech recognition errors and for clarifying vague questions, based on only large text knowledge base. We introduce two measures to make dialogs for fixing recognition errors. An experimental evaluation shows the advantages of these measures.
