Development and Evaluation of a Source Code Plagiarism Detection System for Programming Classes

我开发了一个专门针对编程课的抄袭检测系统，以减轻教师的身心负担。我的方法利用了基于作者编码风格的特性。我对系统进行了多次改进和评估，并取得了积极的效果。我提出了一种新的方法，使用我的方法来评估基于算法相似性的现有方法的输出，以防止误判。问卷调查的结果和与教师讨论的结果表明，我们的方法很可能减轻了教师和学生的心理负担。

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.
