AI graders get top marks for scoring essay questions  – New Scientist

It seems like this has some pros and cons. Text analysis has advanced to the point where grammar and structure can be scored reliably, but meaning still gets left out. I would think you could do even better than this by searching wikipedia for correlations in concepts. Or perhaps ironically, scanning online essay databases people use for cheating. This could have the duel benefit of scoring the meaning somewhat as well as searching for exact matches which could indicate cheating.

But even if these tools are used in combination with the teachers grading essays manually it should save them lots of time. All the grammar markups could be thrown up on the essay so the teacher doesn’t waste time correcting those and tries to asses the orthogonal problem of how good the student’s ideas or comprehension are.
