We share with (Sanchis-Trilles et al., 2008) the idea of making a more sophisticated use of the mouse actions performed by the user while interacting with the system, and with (González-Rubio et al., 2013) the common ITP formulation for both phrase-based and hierarchical MT models.
we significantly modify the prefix-based ITP implementation presented in the latter work to support the proposed unrestricted proof-reading protocol.
