代码抄袭检测技术研究及在实验教学中的应用

为了辅助教师对学生实验代码抄袭检测。根据已有的检测算法,提出一种以多行为单位,对代码进行标准化、数字化、预处理,并使用基于指纹的方式进行比较的方案。该方案不仅能够检测代码的相似度,同时能够给出抄袭的行数。经过实验教学应用,该方法能够检测大部分学生抄袭的情况,能够实际应用。

Research on Code Plagiarism Detection and Application in the Experimental Teaching

In order to assist teachers to check whether students plagiarize experimental codes or not,this paper proposes a code detection program by comparing digital fingerprints,based on the existing detection algorithms.In this program,the codes were normalized,digitized and preprocessed in rows for unit.The program can not only check the similarity of codes,but also show the plagiarized lines.The application of experimental teaching indicates that the method is capable of checking out majority of students’ copying conditions and therefore it’s practical.
