* Trimmed coverage means the coverage the morphological analyzer after being trimmed according to the bilingual dictionary of the pair, that is, only containing stems which are also in the bilingual dictionary.
⚫
* Testvoc-lite (<code>apertium-tat-rus/testvoc/lite$ ./testvoc.sh</code>) for a category means taking one word per each sub-category and making the full paradigm of the word pass through the translator without debug symbols. E.g. "testvoc-lite for nouns clean" means that if we leave only one word in each of the N1, N-COMPOUND-PX etc. lexicons, they will pass through translator without [@#] errors.
⚫
* Evaluation is taking <math>n</math> words and performing an [[evaluation]] for post-edition word error rate (WER). The output for those <math>n</math> words should be clean.

Workplan (GSoC 2014)

This is a workplan for development efforts for the Tatar to Russian translator in Google Summer of Code 2014.

Major goals

  • Clean testvoc
  • 10000 top stems in bidix and at least 80% trimmed coverage
  • Constraint grammar of Tatar containing at least 1000 rules, which makes 90-95% of all words unambiguous, with at least 95% retaining the correct analysis.
  • Average WER on unseen texts below 50
