Apertium

Apertium is an open-source machine translation platform, initially aimed at related-language pairs but recently expanded to deal with more divergent language pairs (such as English–Catalan). The platform provides (a) a language-independent machine translation engine (b) tools to manage the linguistic data necessary to build a machine translation system for a given language pair and (c) linguistic data for a growing number of language pairs.

Current released language pairs include:

* Spanish–Catalan
* Spanish–Portuguese
* Spanish–Galician
* Occitan–Catalan
* French–Catalan
* English–Catalan
* Romanian-Spanish

With the following under development:

* English-Afrikaans
* French-Spanish
