Hello, 

The trained data repository tessdata-fast has two trained data for same language such as eng.traineddata and English.traineddata. I could not find the explanation about the difference. 
In case for Japanese, the difference of results between the Japanese.traineddata and the jpn.traineddata were often not small.  
Where should I look for the description about it?

Please see https://github.com/tesseract-ocr/tessdata/issues/62#issuecomment-319442674

Initial capitals indicate the one model for all langs in that script, so eg Latin is all latin-based languages except vie, which has its own Vietnamese. Most of the script models include English training data as well as the script, but not for Cyrillic, as that would have a major ambiguity problem. Devanagari is hin+san+mar+nep+eng, and Fraktur is basically a combination of all the latin-based languages that have an 'old' variant, etc... I would be interested to hear more feedback on the Script models
