Some thirteen years ago I wrote GFU-LAB, a parser for a formalism very akin to Lexical-Functional Grammar (LFG) for use in a Computational Linguistics course that I taught at that time at the Universitat Politècnica de Catalunya (Technical University of Catalonia), in Barcelona. That piece of software was implemented in Arity Prolog for MSDOS platforms. It was also made freely available through the Garbo FTP software repository.

I have recently transferred the code to SWI-Prolog and decided to make the code available for all the people interested. This version of GFU-LAB has been worked out in LINUX, but its runs well in Windows. You are free to download it and use it. If you perform any modification in the code I am very interested in hearing about it.

In carrying out the adaptation I have only introduced minor changes in the original code, not without realizing that GFU-LAB could be substantially improved by adding some of the insights of recent LFG theory (such as, for instance, Lexical Mapping Theory). Another (more mundane) refinement should be the integration of GFU-LAB in a window environment (something that SWI-Prolog makes possible by virtue of his graphical extension XPCE).
