集合随机抽选法在智能组卷中的研究

Research on set at random algorithm in intelligent generating test paper

提出了一种基于集合的随机抽选的智能组卷算法,该算法是以集合论为基础,将智能组卷的要求形式化,将满足要求的试题组成试题库集合,采用集合随机抽取算法进行试题组卷。该算法与传统的组卷算法在生成试卷的效率上进行了比较,同时针对由算法所引起的修改操作困难提出了解决方法。将用户的组卷要求用集合的形式描述出来,满足要求的试题被组成试题库集合,采用集合随机抽取算法进行自动组卷。

Computer test construction as one of important application on computer assisted instruct ion, its key technology lies in intelligent generating test paper. An intelligent algorithm of generating test paper based on set is presented. The algorithm using set to formalize the require of intelligence generating test paper, a set of test paper with the satisfied ones is organized and test paper is generated by the algorithm of choosing randomly in set. The algorithm with traditional algorithm on efficiency of generating test paper is compared. In additional, one way is provided to resolve the difficulty in storing the modification ofdatabase. Generating request ofusers is described as the form of set. The term set generate test paper by adopting the algorithm.
