题库系统试卷自动生成算法研究

Algorithm for automatic test paper generation

组卷是题库系统的一个重要组成部分 ,试卷自动生成算法的好坏直接影响到试题库的性能 .分析了目前题库系统进行自动组卷时存在的一般问题后 ,通过对用户命题要求的研究 ,提出了一种效率和成功率都比较高的试卷自动生成算法 .这个算法首先产生试卷的量化模型 ,再根据这个模型在试题库中进行抽题组卷 。

By analysing the current item pool system, an algorithm has been proposed for the automatic generation of test papers with higher efficiency and success rate to satisfy the requirement assigned by users. The algorithm first generates a quantization model of test papers, then the test questions are selected from item pool according to the quantization model. The random selection and approximate match tactics are used in this algorithm.
