POSITIVE = 'positive'#
pm4py.algo.filtering.ocel.event_attributes.apply(ocel: OCEL, values: Collection[Any], parameters: Dict[Any, Any] | None = None) → OCEL[source]#

Filters the object-centric event log on the provided event attributes values

Parameters:

  • ocel – Object-centric event log

  • values – Collection of values

  • parameters – Parameters of the algorithm, including: - Parameters.ATTRIBUTE_KEY => the attribute that should be filtered - Parameters.POSITIVE => decides if the values should be kept (positive=True) or removed (positive=False)

Returns:

Filtered object-centric event log

Return type:

ocel

pm4py.algo.filtering.ocel.event_attributes.apply_timestamp(ocel: OCEL, min_timest: datetime | str, max_timest: datetime | str, parameters: Dict[Any, Any] | None = None) → OCEL[source]#

Filters the object-centric event log keeping events in the provided timestamp range

Parameters:

  • ocel – Object-centric event log

  • min_timest – Left extreme of the allowed timestamp interval (provided in the format: YYYY-mm-dd HH:MM:SS)

  • max_timest – Right extreme of the allowed timestamp interval (provided in the format: YYYY-mm-dd HH:MM:SS)

  • parameters – Parameters of the algorithm, including: - Parameters.TIMESTAMP_KEY => the attribute to use as timestamp

Returns:

Filtered object-centric event log

Return type:

filtered_ocel
