摘要：In this article, we describe a long-term enterprise at the FernUniversität in Hagen to develop systems for the automatic semantic analysis of natural language. We introduce the underlying semantic framework and give an overview of several recent activities and projects covering natural language interfaces to information providers on the web, automatic knowledge acquisition, and textual inference.
