Dear Wikisourcerers, It's good to hear from you. Wikisource is awesome, as far as I am concerned.

Actually, Tesseract should already have support for Russian and Belarussian "out of the box"; see the 'rus' and 'bel' training data. > We would like to know if you would be interested in exploring collaboration > possibilities.

That has been my experience with training Ancient Greek (for which I have been interested in recognising printing from a variety of time periods). So give Tesseract a whirl, and if it isn't appropriate, or doesn't work for specific scripts, let us know and we can try to figure out a plan. > At the moment it is not very clear how to achieve this. My plan is to rewrite the training documentation very soon, so things should hopefully become clearer on that front. One thing that wikisource could potentially do for us would be provide loads of proofread, freely reusable "ground truth" data to test Tesseract with. Are there programatic ways of getting at the data, for example downloading all page images and corresponding text that is marked as green, for a specific language / script?
