About

Grammatical Framework (GF) is a grammar formalism and a programming language for multilingual computational grammars. It is 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 main syntax rules of over 40 languages with a shared abstract syntax, and its WordNet-based interlingual lexicon includes 24 languages. These resources are freely available as open-source software.

In combination with the linguistic knowledge contained in the RGL, GF software is aimed to help non-linguist programmers to build systems that have high-quality natural language processing as a component. For linguists, GF provides a platform for powerful abstractions and generalizations, including cross-lingual ones.

You will find the GF book a very good companion to your studies (available also as an e-book). However, the book is not a requirement for successful participation in the summer school.

There is no registration or participation fee. However the participants need to support their own travel and stay, including accommodation and meals.
