 +===== Abstract =====
 +
 +Workflow nets, a subclass of Petri nets, are known as attractive models for analysing
 +complex business processes. In a hospital environment,​ for example, the processes
 +show a complex and dynamic behavior, which is difficult to control; the workflow net
 +which models such a complex process provides a good insight into it, and due to its
 +formal representation offers techniques for improved control. We propose a method
 +whose main advantage consists in discovering the workflow Petri nets automatically
 +from process logs. We illustrate the functioning of our method on simulated hospital
 +process logs, containing information about medical actions over time. The results of
 +our experiments indicate that this method is able to discover processes whose
 +underlying models are acyclic and sound WF nets, involving parallel, conditional and
 +sequential constructs. We argue that solutions have to be found for cyclic and free-choice/​non-free-choice workflow nets.
