Basurde[lite], a Machine-Driven Dialogue System for Accessing Railway Timetable Information

We present Basurde[lite], a complete human-machine dialogue system for accessing railway information, based on machine-driven dialogues, a small vocabulary and grammar, and word and phrase spotting based on unrestricted grammars. We give preliminary evaluation results.

Although machine-driven, the system accepts however some flexi- bility: in some cases the user may give a reply not corresponding to the system’s question, and may use out-of-vocabulary words and expressions. The system mimics the user in his choice of time and date formats and language used for place names.
