What is GF?

+ +The Grammatical Framework (=GF) is a grammar formalism based on type +theory. It consists of + +The compiler reads +GF grammars from user-provided files, +and the generic grammar processor performs +various tasks with the grammars: + +GF particularly addresses four aspects of grammars: + +GF provides an easy way to experiment with grammars written in +different formats, including the ubiquitous BNF and EBNF formats. +The GF compilation chart gives a +summary of the supported input and output formats (the nodes in ellipses). + +
+ +For instance, if you want to create a finite-state automaton +in the HTK SLF format (to use for speech recognition), all you have to do +is to write an EBNF grammar in a file foo.ebnf and type +
+  echo "pg -printer=slf" | gf foo.ebnf

Examples and demos

+ +Numeral +translator: recognizes and generates +numbers from 1 to 999,999 in 80 languages. +(The link goes to a live applet, which requires +Java 1.5 plugin. +Here is an example, which does +not require the plugin.) + +

+ +Letter +editor: +write simple letters in English, Finnish, +French, Swedish, and Russian with a few mouse clicks. + +

+ +Demo film +of a multimodal dialogue system built with embedded grammars. + +

+ +Example grammars used in the +GF tutorial. + +

+ +Resource grammar library: +basic structures of ten languages +(Danish, English, Finnish, French, German, +Italian, Norwegian, Russian, Spanish, Swedish). +Resource grammars can be used as libraries for writing GF +applications, +but they can also be useful for language training. + + + +

Executable programs

+ +GF is available for +several platforms: Linux, Mac OS X, Microsoft Windows, and Sun OS. +To get GF, go to the +Download Page. + + +

Quick start

+ +When you have downloaded and installed GF, you can try one of the +quick start examples. + + + +

Source code

+ +The main part of GF is written in +Haskell. + +

+ +The platform-independent graphical user interface is written in +Java. + + +

+ +The Download Page +gives links to source and binary packages, as well as +information on compiler requirements. + +

+ +The publicly accessible + +Darcs repository +has the latest sources and documents. + +

+ +For Java programmers: GF grammars can be embedded in Java programs by using the + +Embedded GF Interpreter. + + + + +

+ + +See the Documentation page. + + + +

Projects and events

+ +
  • WebALT, +Web Advanced Learning Technologies. GF is used as for generating multilingual +teaching material in mathematics. + +
  • TALK = Tools for Ambient Linguistic +Knowledge. GF was used in implementing multimodal and multilingual dialogue systems. + +
  • KeY project on Integrated Deductive +Software Design. GF was used for +authoring informal and formal specifications. More details on the GF +application + +here. + +
  • +Project Efficient +at Tudor Institute, Luxembourg, "atelier de prototypage de transactions d'e-commerce". +GF is used as an authoring tool for business models. + + + +

    Miscellaneous

    + + +
  • + +GFCC: +report on a compiler from a fragment of C to JVM, written in GF. +The compiler source code can be found in the directory +examples/gfcc in the GF grammar library +(see GF download page). + +
  • +The original +GF Xerox Home Page +with the oldest releases of and documents on GF, up to Version 0.54, 1999, +does not seem to exist any more. + + +
  • +Earlier application: + + Natural-Language Interface to the proof editor Alfa. + +
  • +The BNF Converter. +A GF spin-off customized for the description of programming +languages. + +
