... test set a year later with an improved system. We compared the consensus translation with this new translation (last line of Table 2). It can be observed that the consensus translation based on ... system. We sum up the probabilities of the arcs which are labeled with the same word and have the same start and the same end state. These probabilities are the global probabilitie...

... MT evaluation is shown in Figure 1. Perfect MT output and the reference translation entail each other (top). Translation problems that impact semantic equiv- alence, e.g., deletion or addition of material, ... due to the inap- propriate main verb translation. Together with the subject mismatch, MTR correctly predicts a low score (rank 5/5). RTER’s attention to semantic over- lap le...
