Research on discourse relations between clauses, such as cause or contrast, has studied how relations are signaled in discourse. Several corpora include discourse relation annotations: the Penn Discourse Treebank (Prasad et al., 2008) annotates a subset of relations marked by explicit connectives (e.g. âhoweverâ) or understood implicit ones, while the RST-Signalling Corpus (Taboada & Das 2013) annotates the presence of signals exhaustively, but provides no information about the location of signaling devices. We present an annotation effort to anchor discourse signals at all levels, bridging the gap between these two frameworks, and support feature engineering for automatic discourse parsing.
