VIE-DU: Dialog by Unification

VIE-DU is a unification-based natural language consulting system that integrates modern theories of syntax, semantics, and knowledge representation within a unification-based approach.

At the core of the system is an HPSG-inspired grammar of German with considerable coverage. The semantics was extended to also include discourse information.
