Abstract:Data quality determines service quality. With the deep integration of information systems and business processes, a large number of event logs are collected and stored. Process mining technology can extract process models from these logs, thereby optimizing the deployed business processes. This presentation mainly discusses how to improve the quality of event logs. Specifically, it includes two aspects: (1) business evolution issues; (2) Behavioral complexity issues. In response to the issues of business evolution, it mainly explores how concept drift detection technology can find the location of change points in log data, and then divide different process versions. In response to the issues of complex behavior, it mainly explores how trajectory clustering technology can cluster homogeneous behaviors in logs into a cluster, and reduce the complexity of the overall process model by displaying different behavior patterns.
