        abstract = {Discourse relations bind smaller linguistic units into coherent
texts. Automatically identifying discourse relations is difficult, because
it requires understanding the semantics of the linked arguments. A more
subtle challenge is that it is not enough to represent the meaning of each
argument of a discourse relation, because the relation may depend on links
between lower-level components, such as entity mentions. Our solution
computes distributed meaning representations for each discourse argument by
composition up the syntactic parse tree. We also perform a downward
compositional pass to capture the meaning of coreferent entity mentions.
Implicit discourse relations are then predicted from these two
representations, obtaining substantial improvements on the Penn Discourse
Treebank.},
