Title: The Babel-System - An HPSG Fragment for German, a Parser and a Dialog Component
An earlier version of the paper appeared in the proceedings of the Fourth International Conference on the Practical Application of Prolog, London 1996.
The Babel-System is a modularized natural language understanding system written in Prolog. There are modules for
In the paper, I show the overall architecture of the system and give a short overview of how the parser works. In the grammar, I employ the concept of discontinuous constituents which differs from the standard approach for natural language grammars. Although non-standard parsing techniques are applied the system is in fact more efficient than currently known phrase structure based systems.
