Abstract

This paper describes PEGASUS, a spoken dialogue interface for on-lineair travel planning that we have recently developed. PEGASUS leverages off our spoken language technology development in the ATIS domain, and enables users to book flights using the American Airlines EAASY SABRE system. The input query is transformed by the speech understanding system to a frame representation that captures its meaning. The tasks of the System Manager include transforming the semantic representationinto an EAASY SABRE command, transmitting it to the application backend, formatting and interpreting the resulting information, and managing the dialogue. Preliminary evaluation results suggest that users can learn to make productive use of PEGASUS for travel planning, although much work remains to be done.
