Languages of the Volga-Kama region

From Apertium
Jump to: navigation, search

Contents

The languages of the Volga-Kama region include several Turkic and Uralic languages spoken in the Volga-Kama region (along the Volga and Kama rivers) in Russia. These include [varieties of] Tatar, Bashqort, Chuvash, Mari, Komi, Mordvin, and Udmurt (and linguistically, to some extent, Russian).

The 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.

[edit] Status

The ultimate goal is to have multi-purposable transducers for a variety of Volga-Kama 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.

[edit] Transducers

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