针对网络考试系统的即时性和高效性,提出了基于动态试题难度参数的智能组卷算法的设计策略,利用二项分布函数做难度曲线分布模型,结合目标函数对试题多种参数进行优化。根据试卷的整体难度,以试题难度参数为优先,运用试题选题参数调节知识点之间的平衡,试题曝光参数选取出卷频率比较低的试题,从而确定各种题型不同试题难度数量,实现快速自动组卷的目标。
針對網絡攷試繫統的即時性和高效性,提齣瞭基于動態試題難度參數的智能組捲算法的設計策略,利用二項分佈函數做難度麯線分佈模型,結閤目標函數對試題多種參數進行優化。根據試捲的整體難度,以試題難度參數為優先,運用試題選題參數調節知識點之間的平衡,試題曝光參數選取齣捲頻率比較低的試題,從而確定各種題型不同試題難度數量,實現快速自動組捲的目標。

Aiming at the instantaneity and high efficiency of network examination system ,a design strategy for intelli‐gent paper constructing algorithm based on dynamic parameters of item difficulty was proposed .The binomial distribution function was utilized to make the difficulty curve distribution model ,various test question parameters was optimized by com‐bining with the objective function .According to overall difficulty of the test paper ,the difficulty of test questions was priori‐tized;balance among knowledge points was adjusted by applying test question selection parameters and test questions with low appearance frequency are selected through test question exposure parameters .In this way ,the quantity of various ques‐tion types with different difficulties can be determined ,and the objective of rapid automatic paper constructing was realized .
