Following the experimental settings and evaluation metrics in<cite> Bai and Zhao (2018)</cite> , we use two most-used splitting methods of PDTB data, denoted as PDTB-Lin (Lin et al., 2009) , which uses sections 2-21, 22, 23 as training, validation and test sets, and PDTB-Ji (Ji and Eisenstein, 2015) , which uses 2-20, 0-1, 21-22 as training, validation and test sets and report the overall accuracy score.
