Recent work representing discourse relations such as cause or concession in the framework of eRST has connected hierarchical discourse parsing to explicit connectives, such as \u2018be-cause\u2019 or \u2018although\u2019, bringing the framework closer to lexicalized shallow parsing in the tradition of PDTB. However, while PDTB postulates implicit, unexpressed connectives (i.e. an implied although etc.), no such devices are recognized in eRST, and consequently next to nothing is known about the relationship be-tween PDTB-style implicit connectives and eRST-style discourse graphs. In this paper we propose and evaluate an algorithm to align eRST data, which already indicates explicit connectives, to implicit connective annotations following the PDTB guidelines. We also conduct the first evaluation of the relationship between hierarchical RST-style relations and PDTB implicit connectives.<\/p>\n","protected":false},"excerpt":{"rendered":"
