试题库系统中随机抽题算法的设计与实现

Design and Implementation of Random Questions Algorithm of Test Database System

针对职业教育精品网站的特点,提出适应于网络教育的以知识点为核心的自动组卷算法。该算法把题型难度比例、题型个数作为主要控制目标,从而按知识点选题组卷,并运用适当的随机算法组卷策略优化组卷结果。实验表明,该算法依据不同的组卷策略自动生成的试卷,组卷效率、成功率和知识点覆盖率均比较理想。

According to the characteristics of boutique Website of vocational education, presents the network of education adapted to the knowledge point of the core algorithm for automatic test paper. The algorithm makes the difficulty proportional and number of question type as the main control objectives to provide for the topics of knowledge points test paper, and applies the appropriate strategy for optimization of stochastic algorithms composing test paper results. Experiment shows that the test paper efficiency, success rate, and knowledge point coverage of the algorithm which based on a different strategy for automatic generation of test paper are ideal
