基于大学英语网考的智能组卷方法设计

The Design of Intelligent Test Paper Generation for English Test Based on Genetic Algorithm

随着计算机的日益普及和互联网技术的进步,计算机辅助网考在大学英语等级考试中越来越普遍。基于目前大学英语网考组卷过程中存在的组卷问题,分析设计了智能组卷数学模型,以定量的形式表征组卷过程,结合组卷的数学模型以及相应的约束条件引入改进遗传算法,设计智能组卷算法,形成一套基于大学英语网考的智能组卷方法。通过仿真结果分析,该智能组卷方法通过优化迭代,可以快速组合理想试卷,所设计的智能组卷算法不仅组卷质量好,速度也快,很好地反映了学生的真实英语水平。

With the increasing popularity of computers and the progress of Internet technology,computer-aided online test is becoming more and more common in college English test.Based on the problems existing in the process of generating test paper in college English online test,this paper analyzes and designs the mathematical model of intelligent test paper,characterizes the process of generating test paper in a quantitative form,introduces the improved genetic algorithm combined with the mathematical model and corresponding constraints,designs the intelligent test paper algorithm,and develops a set of intelligent test paper method based on college English online test.Through the analysis of simulation results,the intelligent test paper generation method can quickly generate ideal test papers through optimization iteration.The designed intelligent test paper generation algorithm not only has good quality and fast speed,but also reflects the students’real English level.
