This won't help you any, but we were doing OCR and then parsing a PDF dictionary. The vertical space between entries was usually enough larger than the vertical space between lines within a dictionary that we could distinguish these. Except when a dictionary entry might (or might not) have been split between columns or pages... Especially problematic were a couple entries that were more than one column or even one page in length.
