A Two Phases Statistical Approach for Dialog Management

Perception in Multimodal Dialogue Systems (PIT 2008)

Abstract

In this paper, we present a statistical methodology for dialog management. This methodology is based on a classification procedure that considers all of the previous history of the dialog and the result of the queries to the module that controls the application. The classification procedure is divided into two phases to generate the next system turn. We summarize the work that has been carried out to apply this methodology for developing a dialog system for booking sports facilities. A dialog simulation technique has been used to acquire a dialog corpus for this task and to develop a dialog manager following the proposed methodology. The final model has been evaluated using a corpus recorded for the task with real users.

This work has been partially funded by Spanish MEC and FEDER under project TIN2005-08660-C04-02, Spain.
