研究并实现了一种符合实际需求的组卷算法,它是题库建设及计算机自动生成考核试卷的核心技术.该组卷算法的目的是保证自动组卷的快速、合理并符合试卷基本要求和教师专门要求,采用的方法是反复随机筛选法,搜索本卷未抽取的试题,逐一用多个要求的条件判断该题是否符合要求,每搜索一次后若题量未够,则进行下一次搜索并放松条件(即去掉一个判断).在对多门课程题库的多次组卷结果的分析后,该算法能很好地满足在知识点上分布平均,最近曝光度低、难度符合要求,一次抽出的各套试卷之间重复题少.该算法已应用于在电大多门课程的考核出题中,结果表明其减轻了教师的大量重复性工作,而且能保证考核的有效性和合理性.%A algorithm of test paper generation according to the actual demand is proposed.It is the key technology for building a bank of test items and automatically generating an examination paper by computer.The bank of test items and computer autamatically-generating system of test papers are the efficient means to select talents and objectively evaluate teaching level.It embodies the principle of separation between teaching and testing, and provides a direction for the future test.At the same time, the system can reduce a great deal of the periodically repeated work and help improve teaching quality.The basic characteristic of test papers is analyzed.The algorithm of test paper generation and the realization of the algorithm are described The key process and difficult points of the algorithm are explained in detail.
