For predicting sentence similarities, in both variants of the task, word or chunk alignments have extensively been used (Sultan et al., 2015;Sultan et al., 2014a;Sultan et al., 2014b;Hänig et al., 2015;Karumuri et al., 2015;Agirre et al., 2015b;Banjade et al., 2015, and others).
to these systems, we proposed a model that is trained jointly to predict alignments, chunk similarities and sentence similarities.
