对Apriori算法的改进及其实现研究
摘 要：传统的关联规则挖掘Apriori算法时间开销大，提出基于关系代数理论的关联规则挖掘ORAR算法，利用关系矩阵只需扫描数据库一次。通过大量的仿真实验证明改进的ORAR算法是高效的，减少了挖掘大数据集中频繁项集的运行时间。

To Apriori algorithm improvement and realization research
abstract: The traditional connection rule excavates the Apriori algorithm time expenses to be big, proposed excavates the ORAR algorithm based on the relational algebra theory connection rule, only must scan database one time using the relational matrix.Through the massive simulation experiment proved the improvement the ORAR algorithm is highly effective, reduced the excavation large number according to the centralism frequent item of collection running time.
