Research Abstract

I developed a plagiarism detection system specialized for programming classes to reduce instructors' physical and psychological burdens. My method utilizes features based on authors' coding styles. I had made several improvements and evaluated the system and obtained positive results. I proposed a new methodology that used my method to evaluate outputs of the existing methods based on algorithmic similarity to prevent misjudgments. The result of a questionnaire investigation and the findings from discussions with teachers suggested a high possibility that our method placed less psychological burdens to both instructors and students.
