I assume you are referring to http://code.google.com/p/tesseract-ocr/wiki/TrainingTesseract ? It's helpful, thanks, and I should have checked what's there first.
My understanding is that: - one dictionary file (eng.word-dawg) is included as part of building the training data, and includes a separation between frequent and infrequent words - there is no guideline explaining what's "frequent" versus not, nor how the two sets interact. Do the frequent words get picked any time the recognized text is two letters away (as opposed to infrequent words where they trigger only if text is one letter away)? Unclear. - there is no mention of the advantages of the eng.word-dawg method versus eng.user-words but I guess eng,user-words is the only option to anyone who is not building his own training data? I'd like to give it a try (using eng.user-words) - the one question I still have is how do results get affected by adding a word to the dictionary? Auto-correct when replacing letters with a low score gets a match? How many corrections per word? Anyone with answers, please share and I volunteer to add to the doc - it's a wiki after all, why do I get a sense that a thick layer of dust covers the doc :-)?
