| 摘 要： | 分析了现有计算机操作题自动阅卷技术存在的功能限制问题。采用形式化机制定义答案描述语言ADL,将ADL和正则式相结合来描述试题答案;采用适配器设计模式结合VBA技术实现多类型数据源的统一采集模型,达到了试题和阅卷系统的松耦合,可以在不修改程序的情况下添加新试题。使用结果表明,系统具有较高的可配置型和可扩展性,大幅提高了计算机技能测评的效率和准确性。

| Abstract: | This paper analyzes flexibility problem in the existing automatic marking system of computer operation exercises.The formalization method is adopted to define the Answer Describe Language（ADL）.The formal language ADL and regular expression are used to describe answers of exercise.The adapter design pattern is proposed to realize the unified data acquisition modal from various data source.Users can add new exercises without modifying source code,because of low coupling degree between the exercises and marking system.Practice results show that the system has high configurability and flexibility,and the marking efficiency and accuracy are greatly improved. |
