Free/open-source rule-based machine translation

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 and even Basque→English). The platform provides

  • a language-independent machine translation engine
  • tools to manage the linguistic data necessary to build a machine translation system for a given language pair and
  • linguistic data for a growing number of languages and language pairs
