Stage-based discovery of business process models from event logs

Highlights：

• We contribute a modularity-based technique to identify stages from an event log.

• We contribute a technique to discover process models based on stage decompositions.

• We evaluate model accuracy and complexity using public real-life event logs.

• The stage identification technique finds stages close to those identified by humans.

• The discovery technique outperforms existing flat and divide-and-conquer baselines.
