Alignment-Based Precision Evaluator

This node computes the statistical precision information based on the result of alignment-based replayer. Conceptually, the precision of a process model compared to one event log is supposed to be (1) high when the model allows for few traces not seen in the log; and (2) low when it allows for many traces not seen in the log.

Ordered Representation
The representation of the information in the event log (ordered sequences or multi-sets). This option is enabled by default.
The algorithm to calculate the precision. The following options are available:
  • 1-Align Precision.
  • All-Align Precision.
  • Representative-Align Precision.
  • ETC Precision (no invisible/duplicates allowed).
