This is a language pair translating from Tatar to Russian. The pair is currently located in nursery.
Current state
| Last updated | Testvoc (clean or not) | Corpus testvoc (no *, no */@, no */@/#) |
Stems in bidix | WER, PER on dev. corpus | Average WER, PER on unseen texts |
|---|---|---|---|---|---|

- Testvoc = apertium-tat-rus/testvoc/standard/testvoc.sh
- Corpus testvoc = apertium-tat-rus/testvoc/corpus/trimmed-coverage.sh. Corpora can be found in the turkiccorpora repository.
- news = tat.news.2005-2011_300K-sentences.txt.bz2, wp = tat.wikipedia.2013-02-25.txt.bz2, NT = tat.NT.txt.bz2. Others are unambiguous.
- Number of stems taken from the header "aperium-dixtools format-1line 10 55 apertium-tat-rus.tat-rus.dix" produces.
- Development corpus = apertium-tat-rus/corpus (-test = tat-rus-nova.txt, -ref = tat-rus-posted.txt). WER / PER results are given when unknown-word marks (stars) are not removed.
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
Overview
| Weeks 1-6 | Weeks 7-12 | Saturdays | ||
|---|---|---|---|---|
| get categor(y/ies) testvoc clean with one word -> |
<- add more stems to categor(y/ies) while preserving testvoc clean |
disambiguation | lexical selection | adding stems |
| transfer rules for pending wiki tests (focus on phrases and clauses, not single words) | ||||
Weekly schedule

| 2 | 26/05—01/06 | Adjectives, lite | All nouns from tat.lexc |
✓ | 2141 | -- | Not all nouns were added. Around 500 are pending. They require adding stems to rus.dix as well. | |

- Testvoc-lite (
apertium-tat-rus/testvoc/lite$ ./testvoc.sh) 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. - Till midterm, bilingual dictionary and, if necessary, Russian transducer are expanded with translations of stems taken from apertium-tat.tat.lexc.
- Evaluation (except for gisting evaluation) is taking words and performing an evaluation for post-edition word error rate (WER). The output for those words should be clean.
