pm4py.algo.merging.case_relations.algorithm module

class pm4py.algo.merging.case_relations.algorithm.Variants(*values)

Bases: Enum

PANDAS = <module 'pm4py.algo.merging.case_relations.variants.pandas' from '/Users/chris/Desktop/PIS/pm4py2/pm4py/pm4py/algo/merging/case_relations/variants/pandas.py'>

pm4py.algo.merging.case_relations.algorithm.apply(dataframe1: DataFrame, dataframe2: DataFrame, case_relations: DataFrame, variant=Variants.PANDAS, parameters: Dict[Any, Any] | None = None) → DataFrame

Merges the two dataframes (dataframe1 and dataframe2), inserting the events of the second dataframe inside the cases of the first dataframe. This is done using a background knowledge provided in the case_relations dataframe, where the cases of the two dataframes are put in relations. E.g., if in dataframe1 and dataframe2 there are two case ID columns (case:concept:name), they are put in relations by case_relations having two columns case:concept:name_LEFT and case:concept:name_RIGHT

Parameters:

• dataframe1 – Reference dataframe (in which the events of the other dataframe are inserted)

• dataframe2 – Second dataframe (to insert in the cases of the first)

• case_relations – Case relations dataframe

• variant –

  Variant of the algorithm to use, available ones:

  • Variants.PANDAS

• parameters – Variant-specific parameters

Returns:

Merged dataframe

Return type:

merged_dataframe
