pm4py.statistics.ocel.act_utils.aggregate_events(associations: Dict[str, Set[Tuple[str, str]]]) → Dict[str, Set[str]][source]#

Utility method to calculate the “events” metric from the associations.

pm4py.statistics.ocel.act_utils.aggregate_unique_objects(associations: Dict[str, Set[Tuple[str, str]]]) → Dict[str, Set[str]][source]#

Utility method to calculate the “unique objects” metric from the associations.

pm4py.statistics.ocel.act_utils.aggregate_total_objects(associations: Dict[str, Set[Tuple[str, str]]]) → Dict[str, Set[Tuple[str, str]]][source]#

Utility method to calculate the “total objects” metric from the associations.

pm4py.statistics.ocel.act_utils.find_associations_from_relations_df(relations_df: DataFrame, parameters: Dict[Any, Any] | None = None) → Dict[str, List[Tuple[str, str]]][source]#

Associates each activity in the relationship dataframe with the combinations of event identifiers and objects that are associated to the activity.

Parameters:

  • rel_df – Relations dataframe

  • parameters – Parameters of the method, including: - Parameters.EVENT_ID => the attribute to use as event identifier - Parameters.OBJECT_ID => the attribute to use as object identifier - Parameters.EVENT_ACTIVITY => the attribute to use as activity

Returns:

Dictionary that associates each activity to its (ev. id, obj id.) combinations.

Return type:

dict_associations

pm4py.statistics.ocel.act_utils.find_associations_from_ocel(ocel: OCEL, parameters: Dict[Any, Any] | None = None) → Dict[str, Set[Any]][source]#

Associates each activity in the OCEL with the combinations of event identifiers and objects that are associated to the activity.

Parameters:

  • ocel – Object-centric event log

  • parameters – Parameters of the method, including: - Parameters.EVENT_ID => the attribute to use as event identifier - Parameters.OBJECT_ID => the attribute to use as object identifier - Parameters.EVENT_ACTIVITY => the attribute to use as activity

Returns:

Dictionary that associates each activity to its (ev. id, obj id.) combinations.

Return type:

dict_associations
