Our goal in this case is to learn possible rhetorical relations between the sentences produced in the previous stage (which in our data could be either contrast, elaboration or none.)
every related sentence pair in the corpus produced a positive training instance in the form (m 1 , m 2 , relation) in which m 1 and m 2 are messages from one sentence each, and which are found in the nucleus and satellite (or vice-versa) of a inter-sentential rhetorical relation.
