Open AccessCase notion discovery and recommendation: automated event log building on databases
Process mining techniques use event logs as input. When analyzing complex databases, these event logs can be built in many ways. Events need to be grouped into traces corresponding to a case. Different groupin...

Open AccessDiscovering workflow nets using integer linear programming
Process mining is concerned with the analysis, understanding and improvement of business processes. Process discovery, i.e. discovering a process model based on an event log, is considered the most challenging...

Using Event Logs for Local Correction of Process Models
During the life-cycle of an Information System (IS) its actual behavior may not correspond to the original system model. However, to the IS support it is very important to have the latest model that reflects t...

Business process management as the “Killer App” for Petri nets
Since their inception in 1962, Petri nets have been used in a wide variety of application domains. Although Petri nets are graphical and easy to understand, they have formal semantics and allow for analysis te...

Measuring precision of modeled behavior
Conformance checking techniques compare observed behavior (i.e., event logs) with modeled behavior for a variety of reasons. For example, discrepancies between a normative process model and recorded behavior m...

What makes a good process model?
There seems to be a never ending stream of new process modeling notations. Some of these notations are foundational and have been around for decades (e.g., Petri nets). Other notations are vendor specific, inc...

Open AccessSoundness of workflow nets: classification, decidability, and analysis
Workflow nets, a particular class of Petri nets, have become one of the standard ways to model and analyze workflows. Typically, they are used as an abstraction of the workflow that is used to check the so-called...

Open AccessProcess mining: a two-step approach to balance between underfitting and overfitting
Process mining includes the automated discovery of processes from event logs. Based on observed events (e.g., activities being executed or messages being exchanged) a process model is constructed. One of the e...

Open AccessDeclarative workflows: Balancing between flexibility and support
Today’s process-aware information systems tend to either support business processes or provide flexibility. Classical workflow management systems offer good process support as long as the processes are struc...

Open AccessDiscovering colored Petri nets from event logs
Process-aware information systems typically log events (e.g., in transaction logs or audit trails) related to the actual execution of business processes. Analysis of these execution logs may reveal important k...
