TAILIEUCHUNG - Báo cáo khoa học: "Automated Japanese Essay Scoring System based on Articles Written by Experts"

We have developed an automated Japanese essay scoring system called Jess. The system needs expert writings rather than expert raters to build the evaluation model. By detecting statistical outliers of predetermined aimed essay features compared with many professional writings for each prompt, our system can evaluate essays. The following three features are examined: (1) rhetoric — syntactic variety, or the use of various structures in the arrangement of phases, clauses, and sentences, (2) organization — characteristics associated with the orderly presentation of ideas, such as rhetorical features and linguistic cues, and (3) content — vocabulary related to the topic,. | Automated Japanese Essay Scoring System based on Articles Written by Experts Tsunenori Ishioka Research Division The National Center for University Entrance Examinations Tokyo 153-8501 Japan tunenori@ Masayuki Kameda Software Research Center Ricoh Co.
