A free/open-source rule-based machine translation platform

Apertium is a free/open-source machine translation platform, initially aimed at related-language pairs (such as Spanish–Catalan) but which has been expanded to deal with more divergent language pairs (such as English-Catalan). The platform provides

(1) a language-independent machine translation engine (2) tools to manage the linguistic data necessary to build a machine translation system for a given language pair and (3) linguistic data for a growing number of language pairs.
