What is GF

-GF, Grammatical Framework, is a programming language for -multilingual grammar applications. It is -

a special-purpose language for grammars, like YACC, Bison, Happy, BNFC -
a functional language, like Haskell, Lisp, OCaml, Scheme, SML -
a natural language processing framework, like LKB, XLE, Regulus -
a categorial grammar formalism, like ACG, CCG -
a logical framework, like Agda, Coq, Isabelle -

- -

-Don't worry if you don't know most of the references above - but if you do know at -least one, it may help you to get a first idea of what GF is. -

Applications

-GF can be used for building -

[text translators ] -
[speech translators ] -
[natural-language interfaces ] -
[multilingual web pages ] -
[multilingual authoring systems ] -
[dialogue systems ] -
[language training systems ] -
[natural language resources ] -

- -

Availability

-GF is open-source, licensed under [GPL ] (the program) and [LGPL ] (the libraries). It -is available for -

[Linux ] -
[Mac OS X ] -
[Windows ] -
via compilation to [JavaScript ], almost any platform that has a web browser -

- -

Projects

-GF was born in 1998 at Xerox Research Centre Europe, Grenoble in the project -Multilingual Document Authoring. At Xerox, it was used for prototypes including -a restaurant phrase book in 6 languages, -a database query system in 7 languages, -a formalization of an alarm system instructions with translations to 5 languages, and -an authoring system for medical drug descriptions in 2 languages. -

-Later projects using GF and involving third parties include, in chronological order, -

GF-Alfa: natural language interface to formal proofs -
GF-KeY: authoring and translation of software specifications -
TALK: multilingual and multimodal spoken dialogue systems -
WebALT: multilingual generation of mathematical exercises (commercial project) -
MultiWiki: multilingual Wiki for restaurant reviews -
SALDO: Swedish morphological dictionary based on tools developed for GF -

- -

-Academically, GF has been used in four [PhD theses ], and resulted in around -fifty [scientific publications ]. -

Programming in GF

-GF is easy to learn by following the tutorial. You can write your -first translator in 15 minutes. -

-GF has an interactive command interpreter, as well as a batch compiler. Grammars can be -compiled to parser and translator code in many different formats. These components can -then be embedded in applications written in other programming languages. The formats -currently supported are: -

Haskell -
Java -
JavaScript -
Prolog -
Speech recognition: HTK/ATK, Nuance, JSGF -

- -

-The GF programming language is high-level and advanced, featuring -

static type checking -
higher-order functions -
dependent types -
pattern matching with data constructors and regular expressions -
module system with multiple inheritance and parametrized modules -

Libraries

-Libraries are at the heart of modern software engineering. In natural language -applications, libraries are a way to cope with thousands of details involved in -syntax, lexicon, and inflection. The GF resource grammar library has -support for an increasing number of languages, currently including -

Arabic (partial) -
Bulgarian -
Catalan (partial) -
Danish -
English -
Finnish -
French -
German -
Hindi/Urdu (fragments) -
Interlingua -
Italian -
Norwegian bokmål -
Russian -
Spanish -
Swedish -
Thai (fragments) -

- -

-Adding a language to the resource library takes 3 to 9 -months - contributions -are welcome! -
