RE: MT Confidence definition

Hi Dave,

In the case of QuEst, for the scenario I have in mind, one would for example perform the MT part with MS Hub, then pass that
information to QuEst and get back a score that indicate a level of confidence for that translation candidate. So that's a step after
Mt and before any human looks at it.

I may be wrong, but "MT Confidence" seems to be a good place to put that information.

Even if QuEst is a wrong example. Having MT Confidence restricted to *self-reported* value seems very limiting. But maybe I'm mis
interpreting the initial aim of the data category.

Cheers,

Hi Yves,
I don't necessarily agree with this based on the example you give in relation to quality estimation in Quest.

Is not the goal of quality estimation to predict the quality of a translation of a given source string for a given MT engine
training corpora and training regime _prior_ to actually performing the translation?

In which case it would be an annotation of a translation but of a _source_ with reference to an existing or planned MT engine (which
you rightly say in response to Sergey can be resolved via the annotatorsRef).

So while the basic data structure of mtConfidence would work for, the use case, name and wording don't i think match the use of MT
QE.

Declan, Ankit could you comment - I'm not really an expert here, and not up to speed on the different applications of MT QE.

cheers,
Dave
