This paper presents an intelligent system for information retrieval based on human-machine dialogue through spoken language with novel features such as use of key concepts, unknown word processing, dialogue management through user and system modeling, and automatic acquisition of knowledge to adapt the system to individual users. It then describes an experimental system constructed to implement these features and to demonstrate their feasibility.
