针对传统的编程题自动评分方法没有考虑如何检测考生编程思想以及现有的基于程序理解与基于语义分析模型实现难度大且灵活性差等问题,提出一种基于Java反射机制的采分点匹配技术.评分过程注重动态测试与考生程序的内部结构分析相结合,采用Java反射机制原理与正则表达式匹配的方法进行评分.实验证明评分系统运行稳定,评分结果与人工评分大致相符且具有较好的灵活性.

As for the problem that traditional method of the program automatic grading doesn't con- sider how to detect candidates' programming ideas,as well as the existing models which based on pro- gram understanding and based on semantic analysis are not only difficult to realize but also non-flexible, the key points matching technology is put forward based on Java reflection mechanism. The paper pays attention to the combination of the dynamic test with the programs' internal structure analysis, and by the method of Java reflection mechanism and regular expression to match a score is given. Experimental results show that the system is stable, and the results are consistent with the manual grading, and it also has good flexibility.
