I. Introduction
Over the years, process mining [1] has proven its value as a family of data-driven process analytics techniques. In general, process mining can be subdivided into three main areas: process discovery, conformance checking, and process improvement. The main input to this family of analytics techniques is the so-called event log that contains the process execution data. In its simplest form, an event log is a sequence of events characterized by a case identifier, indicating the unique process instance, the label of the executed activity, and a timestamp (Table I). The sequence of events having the same case identifier is called a trace. A simple event log showing the case identifier, executed activity, and execution timestamp.
