Abstract :
On the face of it, scoring student essays would seem to push AI capabilities to their limits. After all, students express themselves through their writing in vastly different ways. Furthermore, they might misunderstand the essay questions they´ve been asked to write about, or drift off the topic in the course of writing. Even so, for decades now, researchers have known ways to automatically evaluate student writing. What´s been lacking, explains Tom Landauer, executive vice president at the Knowledge Technologies group ol Pearson, is the computer processing power to make grading practical. Processing power has now become a nonissue, of course. LSA is one of many techniques that researchers are employing to advance the state of automated essay grading.
