A system for comparing, and generating pairwise revision markings with respect to, an original text segment and a revised text segment that can include identifying pairwise unchanged text, marking the pairwise unchanged text in the revised text segment with a distinct visual style that signifies its status as such, attempting to successively identify pairwise text divergence points and pairwise text convergence points within the original text segment and the revised text segment, and taking further steps with respect to text that occurs between a pairwise text divergence point and a pairwise text convergence point and/or after a pairwise text divergence point (which steps can include copying text from the original text segment into the revised text segment and marking the copied text, if any, with a distinct visual style that signifies such text as either deleted text or inserted text, as applicable).
