"22-year old mechanical engineering major Luis Tandalla (University of New Orleans) created an algorithm that improves computerized grading of short essays. With this invention Tandalla has tackled one of the major problems with online education: the grading of huge numbers of students. He won a $50.000 prize for this solution at the Kaggle competition site.
While it is easy to have thousands or even millions of students following an online course, it is extremely difficult to test these virtual students on a massive scale. Computers are of limited use when it comes to assessing students’ answers."
Comment: Almost sounds too good to be true. Would love to hear more about this. Is it based on good old latent semantic indexing or does he use a completely novel approach? Anyone? (peter sloep, @pbsloep)
