Abstract:
|
Statistical user simulation is a promising
methodology to train and evaluate the
performance of (spoken) dialog systems.
We work with a modular architecture for
data-driven simulation where the "intentional" component of user simulation includes a User Model representing userspecific features. We train a dialog simulator that combines traits of human behavior such as cooperativeness and context
with domain-related aspects via the
Expectation-Maximization algorithm. We
show that cooperativeness provides a finer
representation of the dialog context which
directly affects task completion rate. |
