抄録

Companies are now able to gather a lot of business process's execution data (calledevent log) by managing them with information systems. In addition, they seek to analyze theirprocess by leveraging event log to improve their processes (e.g. reducing waiting time and costs).However, there are many cases where process management systems record work suspending, butdo not record specific reason for that suspending. Hence, we propose the extracting representativeworkers' activity patterns method for understanding the activity of workers during work suspend-ing. The method takes into account the order of work with Damerau ? Levenshtein distance.Analysts are able to understand the cause of the work stoppage by comparing the extracted pat-terns with the process flow. We could find the workers' activity patterns which is along work flowof the process in the empirical evaluation.
