What is GF

What is GF?

+

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

-
    -
  • a special-purpose language for grammars, like +multilingual grammar applications. It is +

    +
      +
    • a special-purpose language for grammars, like YACC, Bison, Happy, BNFC, but not restricted to programming languages -
    • a functional programming language, like +
    • a functional programming language, like Haskell, Lisp, OCaml, SML, Scheme, but specialized to grammar writing -
    • a development platform for natural language grammars, like +
    • a development platform for natural language grammars, like LKB, XLE, Regulus, but based on functional programming and type theory -
    • a categorial grammar formalism, like +
    • a categorial grammar formalism, like ACG, CCG, but specialized for multilingual grammars, -
    • a logical framework, like +
    • a logical framework, like Agda, Coq, Isabelle, but equipped with concrete syntax in addition to logic -
    • a platform for machine translation, like +
    • a platform for machine translation, like Moses, Apertium, but based on deep structural analysis (and usually applied for limited fragments of language). -

Applications

-

-GF can be used for building -

- - -

Availability

-

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

-
    -
  • Linux -
  • Mac OS X -
  • Windows -
  • Android mobile platform (via Java; runtime) -
  • via compilation to JavaScript, almost any platform that has a web browser (runtime) -
- -

Projects

-

-GF was first created 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, -a database query system, -a formalization of an alarm system instructions with translations to 5 languages, and -an authoring system for medical drug descriptions. -

-

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

-
    -
  • GF-Alfa: - natural language interface to formal proofs -
  • Efficient: - authoring tool for business models. -
  • GF-KeY: - authoring and translation of software specifications -
  • TALK: - multilingual and multimodal spoken dialogue systems -
  • WebALT: - multilingual generation of mathematical exercises (commercial project) -
  • SALDO: - Swedish morphological dictionary based on rules developed for GF and - Functional Morphology -
  • MOLTO: - multilingual online translation -
  • REMU: - reliable multilingual digital communication. -
-

-Here is a talk -about GF at XRCE, -14 years later. - -

-Academically, GF has been used in at least ten PhD theses and resulted -in more than a hundred -scientific publications (see GF publication list). -

-

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, in particular the Android platform -
  • JavaScript -
  • 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 -
- -

Getting help

-

-If you need some help with GF, the first places to start are the Tutorial and Reference pages. -The printed book contains all the material in the tutorial and some extra bits, and is the recommended reference for GF.

-

-We run the IRC channel #gf on the Freenode network, where you are welcome to look for help with small questions or just start a general discussion. -IRC logs (in raw format) are available here. -If you have a larger question which the community may benefit from, we recommend you ask it on the mailing list. -

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 -
