== TODO ==
* More transfer rules

== ONGOING ==

* Transfer rules
* Some lexical selection rules
* Collecting more bidix
** Adding only most-frequent words from kazakh wiki hitparade until 85% coverage is reached

== DONE (+Notes & Comments) ==
* Made a script to calculate WER for each line of the kaz-uzb.txt file to see what sentences are causing the most problems.
* Translating big Kaz text into Uzb
** Aside from those small texts obtained from parallel corpora
** For better WER/PER calculation
** For checking transfer rules
** Started with readily available small JaM Story
*** Azmat and Oygul story in our case
*** Added 47 sentences from that.
** Chose Nur-Sultan(capital city) article of Kazakh Wiki for that.
*** Split the article into sentences, translated into uzb manually.
*** Added 112 sentences out of Nur-Sultan text.
** Used QED parallel corpus form internet.
*** Manually selected sentences and corrected their translations.
*** Added 90 sentences from this.
** Made 250 sentences in total, stopping this here.
* Tried finding parallel corpora:
** ''https://opus.nlpl.eu/''
*** KDE4: Not good: ''https://opus.nlpl.eu/KDE4/v2/kk-uz_sample.html''
*** MozillaI10: Nope
*** '''QED''':
**** kk-uz.tmx file
**** Good, Gonna use this, but needs manual selection and corrections on translations.
*** TED: the same file with QED.
*** The rest is also not good, just one-word translation mostly.
* Lexical selection rules for kaz-uzb
** Created a script to analyse bidix and find ambiguous stems.
** Created a script that generates lexical selection rules from manually chosen stems
** Rules added in kaz-uzb.lrx for 1565 words.
** Rules added in uzb-kaz.lrx for 1295 words.
* '''Apertium-dixtools:'''
** ''https://wiki.apertium.org/wiki/Apertium-dixtools''
** Fixing bidix(deduplicating, removing empty lines):
apertium-dixtools fix apertium-kaz-uzb.kaz-uzb.dix apertium-kaz-uzb.kaz-uzb.dix.fixed
** Sorting bidix(aligning too):
apertium-dixtools sort -alignBidix -ignorecase apertium-kaz-uzb.uz-uzb.dix apertium-kaz-uzb.kaz-uzb.dix.sorted
* Sorting+Deduplicating the bidix for future purposes:
** Bidix count before deduplication: 11008
** Fixing the bidix:
*** Removed 1501 entries in section main
** Bidix count after deduplication: 9507
** Sorted+Regrouped the dix.
* Made a script to calculate DixCount, Coverage, WER/PER at once
* '''Calculating WER/PER:'''
