Compared to statistical machine learning-based methods (Kushman et al., 2014;Mitra and Baral, 2016;Roy and Roth, 2018;Zhou et al., 2015;Huang et al., 2016) and semantic parsing-based methods (Shi et al., 2015;Koncel-Kedziorski et al., 2015;Roy and Roth, 2015;Huang et al., 2017), these methods do not need hand-crafted features and achieve high performance on large datasets.
they lack in capturing the specific MWPs features, which are an evidently vital component in solving MWP.
