Discovering processes with high-level process modeling languages • Sub-processes – Cancellations • Timers • Collaborations (+ Resource perspective) • Data perspective • … 2

Discovering sub-processes (cancellation) How to discover a sub-process, which is connected with the main process by incoming and outgoing control flows? 3

Discovering sub-processes (cancellation) 4

Discovering sub-processes (cancellation) • Noise and incompleteness of a transition system. • How to decompose a transition system? Remove noise and repair a transition system Automatically decompose a transition system Build a process model Construct a high -level process model 5

Why BPMN? • Holistic view on the process • Understandable by wide audience of analytics and developers • Graphical notation and executable format at the same time • Control-flow has formal semantics is based on the concept of token • Was created on the basis of preceding workflow languages and is rather expressive • Is supported by a significant number of tools and is widespread 6

The BPM Academic Initiative Model Collection Do not consider Choreography and Conversation diagrams for the first time, only BPMN processes and their collaborations within one diagram. 7
