  Automated Essay Scoring

    Automated Essay Scoring (AES) is a very critical research tool for educational testing, course instruction, and psychometrics. The system is composed of a Chinese word segmentation and speech tagging system, a fault-tolerant Chinese grammar parser, and a Chinese spell-check and correction tool. When this AES is used to score essays, the accuracy is up to 97% and within one-point difference from the manual scoring. The error type analysis can serve as a self-improvement reference to teachers.
