基于改进蚁群算法的英语考试自动组卷系统

Automatic Generation System for English Test Papers Based on Improved Ant Colony Algorithm

基于改进蚁群算法设计了英语考试自动组卷系统,满足英语考试自动组卷的要求,提高了英语考试自动组卷效率。系统管理人员通过用户管理模块实现用户权限认证;认证成功后通过题库管理模块实施英语考试试题的添加、更新、修改、删除、统计等操作;试卷管理模块按照组卷策略抽取英语考试试题,依据组卷目标,采用改进蚁群算法,通过有效更新信息素,解决自动组卷中试题重复率高问题,完成英语试卷的自动智能化组卷,以及测评后英语考试试卷的评分。实验结果说明:该系统组卷成功率高,平均组卷时间低至15 ms,可提高英语考试自动组卷效率,系统负载较低,相比人工试卷,该系统试卷的同一类学生的考试成绩较高。

An automatic test paper generation system based on improved ant colony algorithm is designed to improve the efficiency of automatic test paper generation and meet the requirements of automatic test paper generation.The system realizes the user authority authentication through the user management module.After the authentication is successful,the English examination questions are added,updated,modified,deleted,counted and other operations are implemented through the question bank management module.The examination paper management module extracts the English examination questions according to the test paper generation strategy,adopts the improved ant colony algorithm according to the test paper generation goal,and solves the problem of automatic test paper generation by effectively updating the pheromone.In order to solve the problem of high repetition rate,the automatic intelligent test paper generation and the scoring of the English test paper after the evaluation are completed.The experimental results show that the system has a high success rate and the average test paper generation time is as low as 15 ms,which can improve the efficiency of automatic test paper generation and reduce the system load.Compared with the manual test paper,the test results of the same kind of students in this system are higher.
