Automatic Essay Scoring

ML approaches: • Qualitative evaluation to a scoring rubric derived from calibrated peer review• Bag of keywords - “cat chased the mouse “ vs “mouse chased the cat”, rare words etc.• Large training sets are counter productive ; learning at the question level.• How does machine learn logical proofs? Metaphors? Humor? • How do you give feedback to students?
