Die Konstanzer LFG-Umgebung

Starting in the mid-1980s, grammars in the DCG, PATR and LFG formats have been implemented at the University of Constance. Experience has shown that translating a grammar specification into machine interrretable code, e.g., Prolog, is difficult and errorprone. A current attempt to let students and research co-workers formulate and test grammar sketches in an abstract formalism directly on the computer promises greater success. Some of the design considerations, background and the implementation in our new system are discussed and compared to other implementations. A special feature 01 the described system is its modularized processing model, which takes synchronic and diachronic derivation al processes into account.
