... words are translated one -to- one. This assumption reduces the explanatory power of our model in comparison to the IBM models, but, as shown in Section 3.1, it helps us to avoid what we call ... the one -to- one assumption: Each word translates to at most one other word. Certainly, there are cases where this assumption is false. We prefer not to model those cases, in order to...
