If you know all the possibilities that your OCR system *could* pick up 
then you could always do something like this...

knownStrings = ['Hello','Goodbye']
out = []
OCR_strings = #new array of strings

OCR_strings.each do |ocr|
  matches,len = 0,0
  knownStrings.each do |known|
    len = known.length
    (len-1).times do |i|
      if (i+1) >= ocr.length
        break
      else
        if ocr[i] == known[i]
          matches += 1
        end
      end
      if matches / known.length > 0.85
        out << known
      else
        out << "!#{known}"
      end
    end
  end
end


...completely untested but i think you know what im getting at
