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

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".

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.
