International translation in the Grammatical Framework (GF)

Grammatical Framework (GF) is a grammar formalism for multilingual grammars, where many languages share a common abstract syntax. The abstract syntax can be used as a translation interlingua. GF was initially designed for domain-specific controlled language systems, but it has in recent years scaled up to wide-coverage translation as well. GF is an open-source project with a world-wide community that has created grammars for over 30 languages. Fifteen of these languages are currently included in a wide-coverage translator, which is available in the GF cloud and also as a mobile app, the GF Offline Translator, with a compact size that fits in a mobile phone. We plan to demo both kinds of systems in the conference.
