分类分段算法在组卷中的应用研究

客观题的组卷算法有很多种，分类分段算法不光能解决组卷中的重复抽题问题，又能解决试题的覆盖面问题。采用分段法，把题库中试题分成N段，每段中抽取一个试题，这样可以解决试题的重复问题。针对不同章节试题覆盖采用在题库中增加一个章节字段，在同一章节中抽取指定试题。同时在组卷中增加一个难度系数,可以对不同章节指定难度系数。以实践为基础，阐述分类分段算法在实际操作中的应用技巧，包括数据库设计、代码设计等。

Research on the Application of Classification and Segmentation Algorithm in Paper Setting

There are many kinds of algorithms in paper setting. Classification and segmentation algorithm not only solves the repeat chance in pumping, but also solves the problem of content coverage. In the stepwise method, the test question database is divided into N segments, each segment of a test sample, which solves the problem of repeated test. According to the different sections of the items cover by adding a chapter field in the database, in the same section extracts a specified item. At the same time, add a difficulty coefficient in the test paper, different section specifies the difficulty coefficient. Based on the practice, expounds the classification skills segmentation algorithm in the actual operation, including database design and code design.
