摘  要:事件日志的预处理是过程挖掘的第一步,事件日志中存在的大量噪音、低频行为对过程挖掘造成了极大的困扰。以往的研究大多是从控制流角度出发,只考虑了活动之间的发生顺序,较少涉及活动所包含的数据属性。由此提出了在控制流关联规则的基础上进行数据流关联规则的挖掘方法,首先基于 Apriori 算法挖掘出具有高度依赖关系的活动集合,再从数据流角度对事件日志进行过滤。具体的实例分析和仿真实验验证了方法的有效性。

Abstract: The preprocessing of event log is the first step of process mining. A lot of noise and low-frequency behavior in event log cause great trouble to process mining. From the perspective of control flow, most of the previous studies only consider the sequence of occurrence among activities, and rarely involve the data attributes contained in activities. Thus this paper puts forward the mining method of data flow association rules based on control flow association rules. Firstly, based on Apriori algorithm, it mines the set of activities with high degree of dependency relationship. Then it filters the event log from the perspective of the data flow. The effectiveness of the method is verified by the actual example analysis and simulation experiments.

Keywords: process mining; association rule; Apriori
