Our work is also closely related to neural language generation, where the encoder-decoder framework (Sutskever et al., 2014) acts as a springboard for many sequence generation models.
we are inspired by the keyphrase generation studies for scientific articles (Meng et al., 2017;Ye and Wang, 2018;Chen et al., 2018Chen et al., , 2019, incorporating word extraction and generation using a seq2seq model with copy mechanism.
