This folder contains the data set as was used for the Process Discovery Contest of 2016 (PDC 2016). The data set contains 10 training logs, 10 corresponding test logs, and 10 corresponding ground truth logs. The logs are all stored using the IEEE XES file format (see either https://www.xes-standard.org/ or https://ieeexplore.ieee.org/document/7740858), while the models are workflow nets (a subclass of Petri nets) stored in the PNML file format (see https://www.iso.org/obp/ui/#iso:std:iso-iec:15909:-2:ed-1:v1:en). In each ground truth log, the additional boolean “pdc:isPos” attribute denotes whether the trace is positive (fits the model, true) or negative (does not fit the model, false).
