摘　　要：简要介绍了数据挖掘技术产生的背景及其分类,阐述了数据挖掘技术中的一个重要分支-关联规则挖掘,研究分析了Apriori算法的不足。利用分组技术对原算法改进,然后把分组Apriori算法应用到数字化图书馆借阅系统中,对读者提供个性化的图书推荐服务。利用某高校已有的图书借阅历史信息,对分组Apriori算法和Apriori算法测试,证明分组Apriori算法相比于Apriori算法确实提高了数据挖掘效率。The background and classification of data mining technology is briefly introduced,and the association rules mining which is an important branch in this technology is described.The defects in Apriori algorithm is researched and analyzed,the original algorithm is improved by grouping technology and the improved algorithm is applied to the digital library system to provide the personalized service for readers.By mean of the information from one university library,the improved Apriori algorithm and the original one are tested.The results show that the improved algorithm does improve the efficiency of data mining.
