Theoretical attention

Dear Colleagues,

I would appreciate if you could devote some of your attention
to explaining the shape of the learning curves seen in statistical
machine translation.

Here below is a link to an extensive experimental study.
These learning curves are different than those I expect from
statistical learning theory
and it would be great to have some model explaining them.
I can think of no better crowd than Pascal2 to answer this question.
