Abstract

The NAUDA1 System is a cooperative natural (German) language database interface for relational databases. The project is carried out at FAW2 - funded by the state of Baden-Württemberg and IBM Germany. This paper describes the extension of a natural language interface to relational databases with respect to its cooperative behavior. We argue that cooperative support of users is especially important for a complex domain such as environmental protection. In order to enrich traditional database reports our system provides dialog-oriented features such as over-answering (providing more information than explicitly requested) and handling of presupposition failure, as well as presentation-oriented features such as natural language responses and geographical maps. Additional information by the system includes (meta-) information about the domain.
