Available translation pairs (translators)

Code snippets

If you've written some stuff for Apertium but haven't got round to actually making a language pair, feel free to make a new page for the language in question and paste it there. Stuff like basic dictionaries, paradigms, rules, hacks etc. are all welcome. See also the Cookbook. See also: Incubator

Staying in touch

• apertium-stuff — mailing list.
• irc.freenode.net #apertium (you can use our CGI::IRC client, or, if you use Mozilla, Firefox or Seamonkey, you may try typing irc://irc.freenode.net/#apertium, which will start the Chatzilla client)
  • There are helper bots on irc: radnik and eleda
• If you find a bug, report it in bugzilla!

Apertium development tools

• Apertium-view - a little GUI application that allows you to view and edit the output of every phase in a translation.
• Apertium-tolk - a simple cousin of Apertium-view. Its emphasis is on user friendliness. It shows the output of a translation as you type.

Wacky ideas

Interested in hacking on a module for apertium that expands the functionality, and the quality of translations that we can generate? Take a look at the following topics:

• Earley-based structural transfer for Apertium
• Prefixes and infixes
• Agglutination and compounds
• Agglutination
• Compounds
• Separable verbs
• Named entity recognition
• Word sense disambiguation
• Orthographic normalisation
• Projects — possible outlines for academic projects.
• Translated IRC! - Here is an XChat script which allows you to translate IRC conversations on the fly, using Apertium.
