摘　　要：时间是事物本身固有的性质,挖掘关联规则的时候把时间因素考虑进去会更符合现实的情况,时态关联规则挖掘是一种考虑带时间约束的关联规则挖掘方法.研究如何对关联规则进行时间上的约束是一个有待解决的问题,运用时态因子对关联规则进行时间上的约束是解决问题的一个办法,在给出时态因子的相关定义后,提出基于时态因子的关联规则相关概念,并给出了一种基于时态因子约束的关联规则的算法.最后结合实验结果,给出了一种关联规则实验结果分析方法,这种分析方法使得所挖掘的实际结果更为直观.Time is inherent in the nature of the things itself.Considering time factor will be more realistic when the association rules are mined.Temporal association rule is a kind of mining method with time constraints.How to constrain time on associtaion rules is an issue to be resolved.Using temporal factors,on association rules is a solution.After defining temporal factors,we propose the concepts of temporal factor and temporal association rules.The algorithm of association rules based on temporal factor is also explained.Finally,experiment results are provided and a method to analyzing the experiment results of association rules is given.The method makes the mined results more intuitive.
