摘　　要：文章针对无纸化考试中运用上下文精确匹配算法进行计算机自动评分的不足,以打字测试自动评分为例,对文本录入过程的添字、漏字、替换录入等情况不同算法的评分效果进行设计分析。运用Visual Basic语言进行打字测试自动评分软件设计,主要实现的功能包括主界面的设计、对照文档的随机读取、历史成绩榜的设计、录入过程的动态监测和测试成绩的评定。文中运用实例不仅详细分析了软件设计的关键技术以及测试过程存在的问题和改进方法,并应用近似串匹配算法给出合理的评分,有效地改进了上下文精确匹配评分的不足。设计过程呈现了一个完整的开发流程,有一定的实用价值。Aiming at the shortage of the exact match algorithm used in computer automatic scoring in the paperless examination,e. g. automatic typing test score,author designed and analyzed the score effect of different algorithm on the conditions of adding,missing or replacing the word and so on in text input process.Visual Basic language was used to make automatic scoring for typing test. The main functions included the main interface design,randomly reading control document,historical performance chart design,dynamic monitoring of the input process and testing score evaluation. Some examples were used to analyze the key technology of software design and the problems existing in the testing process and the improved method. Approximate string matching algorithm was applied to make a reasonable score to effectively improve the deficiencies of context exact match score. The design process presented a complete development process,and had a certain practical value.
