Dear Friends,
This article from the NY Times gives an interesting perspective on Robo-graders for writing exams.

The findings imputed from this commentary corroborate the ecstatic prejudice that humans still do have some inherent advantages over machines; moreover, as Socrates once said regarding pedagogues who espouse robo-graders, “The obvious ambiguity of your statement can be readily discerned by any unbiased observer.”
 
You may read the preceding sentence as an effort by a superannuated pedant to accomodate himself to hypermodern practice.
 
Cordially,
 
Harry
