Running example

A running example

Create an event log as illustrated in Creating event logs. The example log can be downloaded from logs.

To run MINERful, we locate our command shell in the working directory, and launch run-MINERful.sh as follows.

./run-MINERful.sh --in-log-file logs/uniexamplelog.xes --support 0.02 --confidence 1.0 --coverage 0.02 --trace-support 0.125 --trace-confidence 1.0 --trace-coverage 0.125 --prune-with 'hierarchy' --save-as-csv specifications/uni-declarative-specification.csv --save-as-json specifications/uni-declarative-specification.json

Alternatively, short names for options can be used:

./run-MINERful.sh -iLF logs/uniexamplelog.xes -iLClassif 'logspec' -s 0.02 -c 1.0 -g 0.02 -sT 0.125 -cT 1.0 -gT 0.125 -prune 'hierarchy' -oCSV specifications/uni-declarative-specification.csv -oJSON specifications/uni-declarative-specification.json

The rationale for those abbreviations is that the parameter prefixes pertain to the context: -iL for the input (event) Log, -o… for the output format in which discovered specifications are saved.

The mandatory --in-log-file (or -iLF) option locates the input event log. It should be in the XML-based XES format. The default thresholds for event based support, confidence and coverage of the returned constraints are by default 0.05, 0.95, and 0.05, respectively, but can be modified with the --support, --confidence, and --coverage option. The default thresholds for trace based support, confidence and coverage of the returned constraints are by default 0.125, 0.95, and 0.125, respectively, but can be modified with the --trace-support, --trace-confidence, and --trace-coverage option. More information on these metrics and how they are computed can be found in the paper at DOI:10.1007/978-3-031-08848-3_4. Some post-processing can be required to polish the returned set of constraints from redundancies or possible internal inconsistencies (the lower the thresholds, the higher their amount). Here we select the default and faster strategy (-prune), that is to say,hierarchy. The --save-as-csv (-oCSV) and save-as-json (-oJSON) options state where the CSV and JSON versions of the discovered constraints should be saved. The CSV file should show something like this:

Considerations

For the post-processing, other techniques than hierarchy (say, hierarchyconflictredundancy, or hierarchyconflictredundancydouble, the default) can be used. However, this implies more accuracy in the detection (and removal) of the redundant constraints. Generally, the mining per se is very fast. The post-processing takes most of the computation time.

To filter out constraints, the thresholds event and trace based for support, confidence and coverage can be increased. Mind that especially support and coverage tend to be highly sensitive to slight variations in the threshold as they average over the whole set of events or traces.
