In the era of big data and digitalization, many enterprises deploy information systems to better manage enterprise resources and improve operation efficiency. The information system of the enterprise collects and records a large amount of event data in daily operation, such as financial audit logs of the enterprise, supply chain purchase event data and the like. Because business requirements of an enterprise may change, business processes may also change, and a manager needs a current real business process of the enterprise to improve the current business process.
