1st Joint SIG-IL/Microsoft Workshop on Speech and Language Technologies for Iberian Languages
Porto Salvo, Portugal
The adaptation of a stochastic dialog manager to work in a new domain is presented. A dialog manager, previously developed to attend a specific task (queries about train services), has been modified to be used in a different domain (a sport courts booking system). The new manager deals with both tasks, just loading their corresponding bigram models and configuration files. A user simulator technique has been applied to acquire a corpus, and to automatically learn the models. The dialog manager using the learnt models has been evaluated, achieving satisfactory results for using them in an acquisition with real users.
Index Terms: dialog management, stochastic models, domain independence, user simulation.
