Barrachina et al. [2009] , González-Rubio et al. [2013] and<cite> Knowles and Koehn [2016]</cite> present an interactive NMT model with the uni-directional interaction protocol (UniDiR), in which users can only interact with the model from left to right. In our proposed model, human can revise the most critical mistake first in arbitrary position of the sentence; and after that the whole sentence will updated, fixing minor mistakes automatically.
