摘要
本文首先对聚类分析的概念、形式、分类和应用做了简要介绍，其中重点介绍了两步聚类的原理和使用，然后用实证的方法研究两步聚类在考试作弊答案分类中的应用。实证表明：两步聚类能快速得出分类，将分类结果借助自编程序对作弊考生进行归类，其结果和人工分组的结果比对后完全一致。由此得出结论：用两步聚类辅助自编程序的方法进行作弊答案分类切实可行，快速而准确。
This paper briefly introduces the concept, form, classification and applications of Cluster Analysis, which highlights the principles and the use of Twostep cluster method. It uses empirical methods to specify the applications of TwoStep cluster in elassifing the exam cheating answers. The study show that the Twostep cluster method can quickly get the classification, then we use program to assist it to determine which group the candidates are divided into. By comparing the results between this method and traditional manual grouping method, we find the results are same.The final conclusion is that this method applies in classifing the cheating answers is practicable, fast and accurate.
