程序代码转换技术的研究与实现

程序代码转换技术是程序代码抄袭检测技术中的一个重要部分。程序代码转换技术就是把一个程序看作一个文本串,然后再通过一定的文法分析将这个文本串转换成描述程序基本信息的标记串的过程。目前已有多个较有效的抄袭检测系统,如：Jplag,MOSS,YAP等等,但是这些系统中对如何把程序代码进行转换成串的,并没有详细的介绍。本文针对这种情况设计了一个实验系统来实现程序代码转换技术,并进行了验证。

Code conversion technology's research and implementation

Program code token technique is an important component in the detecting program similarity technique.It mean that the programming code as the text string will be used grammar analysis method to convert such text string to the token what can describe basic information and properties of the programming code.At present there are many efficient detecting program similarit system,such as Jplag,MOSS,YAPetc.But these system don＇t intrcduce how to convert program code token to string in detali.So this paper implement a experiment system and demonstrate it.
