New software EdX grades tests, essays automatically - Colleen Fell, Daily Nebraskan

Waiting weeks for exam results may become a thing of the past. EdX, a nonprofit company founded by Harvard University and the Massachusetts Institute of Technology, recently unveiled auto-grade software. The software uses artificial intelligence to automatically grade essays and short-answer questions. The system’s functions are simple. An instructor must first manually grade 100 essays or other written pieces. The EdX system then bases its grading on how the instructor previously graded. http://www.dailynebraskan.com/news/article_e4f5e06a-a24e-11e2-8d26-0019bb30f31a.html
