For dialogues with multiple interlocutors, extraction of their discourse structures could provide useful semantic information to the "downstream" models used, for example, in the production of intelligent meeting man-agers or the analysis of user interactions in online fora.
despite considerable efforts on computational discourse-analysis (Duverle and Prendinger, 2009;Joty et al., 2013;Ji and Eisenstein, 2014;Surdeanu et al., 2015;Yoshida et al., 2014;Li et al., 2016), we are still a long way from usable discourse models, especially for dialogue.
