Knowledge Acquisition in the System VIE-LANG

In this paper an automated knowledge acquisition system for the Natural Language Dialogue System VIE-LANG is described. Data-driven processing of natural language requires a large and detailed body of knowledge. To build up a complete knowledge base for any real world application by hand is a very cumbersome task. In order to ease the acquisition of new knowledge we have developed a system which is able to extend an existing knowledge base in an automated way. The user who inputs the data needs no specific knowledge of the system or the way data are represented in it. The approach is described in some detail and further explained by means of an example.
