摘要
在网络教育高速发展的背景下,主观题自动评分算法是实现网络教育在线考试系统的关键技术,因此主观题自动批改技术以及自动评分算法日益受到广泛的关注。首先介绍主观题自动评分技术及其原理,然后针对目前网络考试系统中主观题自动评分面临的问题进行分析,并结合动态规划算法,提出基于语义脉络的主观题自动评分算法,以便为教师和学生提供帮助。
With the rapid development of network education, automatic scoring algorithm of sub- jective questions has become the key technology to realize online examination in network educa- tion; consequently, automatic assessment technology and automatic scoring algorithm of subjec- tive questions have attracted great attention from people of different walks. The technology and principles of automatic scoring technology of subjective questions are introduced in this paper, and the problems that subjective assessment faces in network examination system are analyzed. The automatic scoring algorithm of subjective questions is put forward hereafter based on seman- tic context and dynamic programming algorithm. Such an algorithm is able to provide help for teachers and students.
