@jbreiden @alexanderP - FYI - regarding problem with packaged traineddata for kur_ara.

[AlexanderP]

@Shreeshrii I understood correctly. trainedata need to change in packages? tesseract-ocr-kur-ara -> tesseract-ocr-kur tesseract-ocr-kur -> tesseract-ocr-kur-ara

[Shreeshrii]

There is no traineddata for kur in tessdata_fast.

I will unpack and convert the dawgs to word list and see if it is possible to correct kur_ara files.

Please do not make any change yet.

@AlexanderP

tesseract-ocr-kur-ara -> tesseract-ocr-kur

Yes, the above change can be made. Currently kur_ara has Latin text only.

tesseract-ocr-kur -> tesseract-ocr-kur-ara

This cannot be done since there is no kur traineddata in tessdata_fast.

@jbreiden @theraysmith

Should I build kur_ara from the ara.traineddata eg. by replacing the wordlist?

Or is there an updated set of Arabic script traineddatas that can be uploaded before 4.0.0 release?

ref: https://github.com/tesseract-ocr/langdata/issues/83#issuecomment-320818183

I was going to push until I discovered a bug with the RTL word lists. Then I also need to integrate this issues list, that I haven't looked at in a while, and rerun training.

[amitdo]

Maybe it should be 'kur_lat'.

ok

[stweil]

Was this issue solved by the renaming?

[Shreeshrii]

kmr is Kurdish in Latin script. Renaming has fixed that issue.

kur was Kurdish in Arabic script in Tesseract3. We have still not restored kur or kur_ara.

[stweil]

So you suggest to restore https://github.com/tesseract-ocr/tessdata/blob/3.04.00/kur.traineddata to the master branch of tessdata?

[Shreeshrii]

That will not work since Arabic script in 3.04 relied on cube which is no longer in codebase.

I will try to recreate using the wordlist and training text by fine-tuning.

ckb is the preferred prefix rather than kur_ara

My finetuned training gives improved results compared to official ara and script/Arabic traineddata on the synthetic eval set.
