tesseract data language model sources

[abram stern]

Hi tesseract community,

I'm working on a research project about OCR and I'm wondering where the included data models (eg 'fast', 'best') come from -- or put another way, what source material is used for training them?  I haven't been able to find this documented anywhere and am interested to know if it involves public domain corpora, data obtained through book scanning, or other sources.

Best regards,

Abram
