Abstract

An integrated scoring function is proposed so that all components of the spoken dialogue system can be jointly considered. Based on this scoring function, the decision in response to a user request is made in the maximum a posteriori (MAP) criterion. Moreover, instead of shallow word-level analysis or simply keyword or keyphrase matching, a deeper analysis is performed in our system by integrating a robust parser and a semantic interpreter. We also show that integration of these two components can be done straightforwardly with the proposed integrated scoring function
