大型数据库关联规则开采技术研究

The Technique of Association Rules Mining in Large Databases

在大型数据库关联规则开采过程中，采用动态项目集计算算法寻找大项目集，以空间换取时间方法提高执行效率．同时，用坚信度作为构造关联规则的依据，更好地反映逻辑上的因果关系．

The technique of mining association rules in large databases is investigated. From a func- tional perspective, the method is developed, based on itemset counting algorithm for finding large itemsets in order to improve efficiency by giving up space to get time. From a semantic perspective, the conviction is used for the standard of generating association rules that are normalized based on both the antecedent and the consequent.
