To mitigate this limitation, structural (dependency or constituency) information in a sentence was exploited and witnessed partial success in various tasks (Goller and Kuchler, 1996;Yamada and 1 Our code for experiments on the SICK dataset is publicly available at https://github.com/amulyahwr/ acl2018 Knight, 2001;Quirk et al., 2005;Socher et al., 2011;Tai et al., 2015).
alignment techniques (Brown et al., 1993) and attention mechanisms (Bahdanau et al., 2014) act as a catalyst to augment the performance of classical Statistical Machine Translation (SMT) and Neural Machine Translation (NMT) models, respectively.
