Similar observations can be made with respect to Chambers and Jurafsky (2009) and Kasch and Oates (2010), who also study a single discourse relation (narration), and are thus more limited in scope than the approach described here.
as their approach extends beyond pairs of events to complex event chains, it seems that both approaches provide complementary types of information and their results could also be combined in a fruitful way to achieve a more detailed assessment of discourse relations.
