Apertium (http://www.apertium.org) is a free software (GPL) machine translation platform; it was initially designed to translate between the Romance languages of the Iberian peninsula, but is now being used for more distant pairs.

Who is developing it ?

The Apertium engine is being developed in the Transducens research group at the Department de Llenguatges i Sistemes Informàtics within the Universitat d'Alacant and also by the spin-off company Prompsit Language Engineering. Linguistic data are being developed by Transducens, the Seminario de Lingüística Informàtica of the Universidade de Vigo, the Institut Universitari de Lingüística Aplicada at the Universitat Pompeu Fabra in Barcelona, along with a number of companies including Prompsit Language Engineering, Imaxin|software and Eleka Ingenieritza Linguistikoa, and independent free software developers both in Spain and abroad.

Funding

The Spanish Ministry of Industry, Tourism and Commerce funded the development of the engine and three initial language pairs: Spanish-Catalan, Spanish-Galician and Spanish-Portuguese. The project has also received funding from: the Universitat d'Alacant, the Generalitat de Catalunya (Government of Catalonia) to improve the engine for distant pairs and to develop language pairs such as English-Catalan, Occitan-Catalan and Occitan-Spanish, the Romanian Ministry of Foreign Affairs to develop translators between Spanish-Romanian and Catalan-Romanian.

Currently supported languages

There are currently seven supported translation pairs published using the Apertium platform. These are:

• Spanish-Catalan
• Spanish-Portuguese
• Spanish-Galician
• Catalan-French
• Catalan-Romanian
• Spanish-Romanian
• English-Catalan

Other pairs currently under active development, but without a stable release include: French-Spanish, English-Afrikaans, English-Welsh, Catalan-Romanian, Spanish-Basque and English-Polish. Stable pairs (and unstable ones at your own risk) can be tested through our web interface at http://xixona.dlsi.ua.es/apertium/.

How good is it?

The quality of the final translations depends greatly on the amount of time spent in development, and the closeness of the languages. For example Spanish-Catalan has approximately 95% accuracy, but Spanish-Portuguese has around 90%. For less related and unreleased pairs such as English-Afrikaans, the accuracy, excluding unknown words is somewhere around 70%.

Downloading

Current versions of the engine, linguistic data and documentation can be found on our SourceForge project page (http://www.sf.net/projects/apertium/). Further documentation and discussion can be found both on our wiki (http://xixona.dlsi.ua.es/wiki/) and mailing list (apertium-stuff@lists.sf.net).

Development

The project is always looking for developers who are interested in improving the engine, working on new language pairs (especially those involving less-used or under-resourced languages), creating interfaces, or adapting the software to fit your needs.

Applications

• Multilingual management of web content such as media
• Rapid localisation of free software
• Translation of documentation between a more resourced language and a less resourced language
