right most of the time without too much effort.
Or at the paragraph level, when two paragraphs are combined into one
(vs. one paragraph being deleted), or one paragraph is split into two
(vs. one paragraph being added), or any of the various other, more
complicated changes that take place.
If you want a high level of accuracy when trying to determine who
added a particular fact (such as "Overall, the city is relatively
flat", which may have started out as "Paris, in general, contains very
few changes in elevation"), you really need to combine automated tools
with human understanding.
