We compare our methods with a few baselines: LSTM: This is the basic LSTM-based deletion method proposed by<cite> (Filippova et al., 2015)</cite> . LSTM+: This is advanced version of the model proposed by<cite> Filippova et al. (2015)</cite> , where the authors incorporated some dependency parse tree information into the LSTM model and used the prediction on the previous word to help the prediction on the current word.
