Grammatical Framework (GF),
a multilingual grammar formalism based on the idea of a shared
abstract syntax and mappings between the abstract syntax and
concrete languages. GF has hundreds of users all over the world.
The GF Resource Grammar Library (RGL) implements the morphology (inflection) and basic syntax (phrase structure)
of 16 languages:
Bulgarian, Catalan, Danish, Dutch, English,
Finnish, French, German, Italian, Norwegian,
Polish, Romanian, Russian, Spanish, Swedish,
These resources are,
freely available as open-source software. More languages are under construction,
in both in-house and external projects.
We are especially interested in EU languages not yet covered by the Resource Grammar Library, namely: Estonian, Latvian, Lithuanian, Irish, Czech, Slovak, Hungarian, Slovene, Portuguese, Greek, and Maltese. Learn more about the RGL status page.
Embedded grammars are parsing and generation programs compiled from GF
grammars and usable as parts of programs written in other languages:
