In this paper we are focused only on semi-supervised domain adaptation -when knowledge from a large labeled dataset in a source domain can be somewhat transferred to help improve the same task on a target domain, which typically has a significantly smaller number of labels.
this paper focuses on domain adaptation for the detection of question duplicates in community question answering forums (Shah et al., 2018;Hoogeveen et al., 2015), as well as for RTE tasks (Dagan et al., 2005;Zhao et al., 2017).
