基于相似度模型的自动阅卷算法

Automatic scoring algorithm based on similarity model

自动阅卷算法一直以来都是各个在线考试系统的重点和难点。这里设计的自动阅卷算法通过解析学生答案中关键字,并计算这些关键字的排布与答案关键字的排布的相似度,给出一个相对合理的分值。经过反复测试调优,该算法提供的分值已经具有相当好的可参考性。

Automatic scoring algorithm is always the emphases and difficulties of various online examination systems. The automatic scoring algorithm we designed gives a reasonable score through the keywords analysis of student answer, the similarity calculation between the arrangement of these keywords and the arrangement of answer keywords. After repeated testing and optimizing, the scores provided by the algorithm have been a very good reference.
