Turkic languages

The Turkic languages include Turkish, Azeri, Uzbek, Kazakh, Kyrgyz, Tatar, Chuvash, Turkmen, Bashkir, Sakha, and several dozen other languages. The languages are related with varying levels of mutual intelligibility. Our goal is to enhance MT coverage of them with apertium.

The ultimate master plan involves generating independent finite-state transducers for each language, and then making individual dictionaries and transfer rules for every pair. The current status of these goals is listed below.

Status

The ultimate goal is to have multi-purposable transducers for a variety of Turkic languages. These can then be paired for X→Y translation with the addition of a CG for language X and transfer rules / dictionary for the pair X→Y. Below is listed development progress for each language's transducers and dictionary pairs.

Transducers

Once a transducer has ~80% coverage on a range of corpora we can say it is "working". Over 90% and it can be considered to be "production".

Getting involved

We have a work plan for developing Turkic-Turkic translators and are working on a how-to for building a Turkic lexicon. Please come talk to us on IRC or contact us on the apertium-turkic mailing list.

Tagset

Rough guide to tagsets in various Turkic language transducers, with an eye to keeping stuff that is basically the same tagged the same. In the following table, ^A stands for Apertium and ^T stands for TRmorph (See also the general tagset list).
