Unlike argument component identification where textual inputs are typically sentences or clauses (Moens et al., 2007;<cite> Stab and Gurevych, 2014b</cite>; Levy et al., 2014; Lippi and Torroni, 2015) , textual inputs of argumentative relation mining vary from clauses (Stab and Gurevych, 2014b; Peldszus, 2014 ) to multiple-sentences (Biran and Rambow, 2011; Cabrio and Villata, 2012; Boltužić anď Snajder, 2014) .
