摘要
通过分析学生作业中存在的抄袭现象,介绍了一种用于抄袭检查的程序的设计和实现。程序能够计算一批程序代码之间的相似程度。为了保证检查精度和运行速度,程序中利用了语法解析、计算数字指纹、求解最长公共子序列等技术。
In accordance with the plagiarism phenomenon, a program was designed and implemented to check it. The program can calculate the similarity in a group of program sources. In order to ensure the accuracy and efficiency, the program was implemented based on the grammar analysis, digital fingerprint and algorithm for longest common subsequences.
