It is -- a **special-purpose language for grammars**, like YACC, Bison, Happy, BNFC, - but not restricted to programming languages -- a **functional language**, like Haskell, Lisp, OCaml, Scheme, SML, - but specialized to grammar writing -- a **natural language processing framework**, like LKB, XLE, Regulus, - but based on functional programming and type theory -- a **categorial grammar formalism**, like ACG, CCG, - but different and equipped with different tools -- a **logical framework**, like Agda, Coq, Isabelle, - but equipped with concrete syntax in addition to logic - - -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 doc/gf-tutorial.html]. 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 lib/] has -support for an increasing number of languages, currently including -+ Arabic (partial) -+ Bulgarian -+ Catalan (partial) -+ Danish -+ English -+ Finnish -+ French -+ German -+ Hindi/Urdu (fragments) -+ [Interlingua http://www.interlingua.com/] -+ Italian -+ Norwegian bokmål -+ Russian -+ Spanish -+ Swedish -+ Thai (fragments) - - -Adding a language to the resource library takes 3 to 9 -months - [contributions doc/projects.html] -are welcome! - -% [doc/10lang-small.png] - - |
