GTU - A workbench for the development of natural language grammars

By Martin Volk, Michael Jung and Dirk Richarz


In this report we present a Prolog tool for the development and testing of natural language grammars called GTU (German: Grammatik-Testumgebung; grammar test environment). GTU offers a window-oriented user interface that allows the development and testing of natural language grammars under three formalisms. In particular it contains a collection of German test sentences and two types of German lexicons. Both of the lexicons can be adapted to a given grammar via an integrated lexicon interface. GTU has been implemented in Prolog both under DOS and UNIX. It was originally developed as a tutoring tool to support university courses on syntax analysis but in its UNIX-version it allows for the development of large grammars. 1 Introduction Any computer system that analyses natural language input (be it a grammar checker or a tool for machine aided translation or the like) needs a formal grammar in order to map the input to a structure that groups it in some meaningful way. However, it is by ..
