| 摘 要： | 文字类主观题的自动批改是实现远程教学系统中在线考试功能的一个关键技术,由于其具有相当的难度,目前国内外在这方面的研究还不是很多,真正实用的系统更少。该文着重对语句相似度的计算进行了深入的研究,利用基于动态规划的语句相似度计算方法实现了文字类主观题的自动批改,测试结果初步达到预期目标。

| Abstract: | Automated assessment technology of the subjective tests based on free texts is one of key techniques of on-line test in the distance teaching system.There is not so much research on automated scoring system of subjective tests and the applied system is much less currently.This paper mainly focused on the research of the metric of sentence similarity,and put forward a model of computing sentence similarity based on dynamic programming.Finally an automated assessment of free texts is implemented by using this model and the testing results have achieved the expectant purpose. |
