摘要
文字类主观题的自动批改是在线考试系统的一个关键技术。本文在研究主观题自动批改技术现状的基础上,提出了一种基于向量空间模型的短语级句子相似度计算方法,并基于该计算方法设计了一种主观题自动批改算法,经验证,实验结果基本达到预期目标。
Automated assessment technology of the subjective tests based on free texts is one of key techniques of online exam system. After analysing the automated assessment of subjective tests, a computational method based on vector space mode is proposed and a arithmetic about the computational method is designed. Finally by a experiment, the testing results achieve the expectant purpose.
