摘要
本文根据考试系统中主观题自动判卷的基于单向贴近度的算法进行改进,提出了加权的单向贴近度的算法.该算法主要考虑了参考答案中各个关键词的重要程度不一样,而给每个关键词赋一定的权值.改进的算法对评分的准确性有一定的提高.
In this paper, by improving the Single Similar Degree algorithm, a weighted Single Similar Degree algorithm is developed for automated assessment of subjective tests in the online exam system, which mainly considers the importance of the key words in the reference answer and gives each of the key words a certain weight. The improved algorithm has more accuracy for the assessment.
