  • parameters – Parameters of the algorithm, including the attribute key and the positive parameter: - If True, returns all the cases containing A and B and in which A was eventually followed by B - If False, returns all the cases not containing A or B, or in which an instance of A was not eventually followed by an instance of B

Returns

Filtered log

Return type

class pm4py.algo.filtering.log.ltl.ltl_checker.Parameters(value)[source]

Bases: enum.Enum

An enumeration.

ATTRIBUTE_KEY = 'pm4py:param:attribute_key'
ENABLE_TIMESTAMP = 'enable_timestamp'
POSITIVE = 'positive'
RESOURCE_KEY = 'pm4py:param:resource_key'
TIMESTAMP_DIFF_BOUNDARIES = 'timestamp_diff_boundaries'
TIMESTAMP_KEY = 'pm4py:param:timestamp_key'
pm4py.algo.filtering.log.ltl.ltl_checker.attr_value_different_persons(log, A, parameters=None)[source]

Checks whether an attribute value is assumed on events done by different resources

Parameters
  • log – Log

  • A – A attribute value

  • parameters

    Parameters of the algorithm, including the attribute key and the positive parameter:
    • if True, then filters all the cases containing occurrences of A done by different resources

    • if False, then filters all the cases not containing occurrences of A done by different resources

Returns

Filtered log

Return type

Parameters
  • log – Log

  • attribute_values – A list of attribute_values attribute_values[n] follows attribute_values[n-1] follows … follows attribute_values[0]

  • parameters – Parameters of the algorithm, including the attribute key and the positive parameter: - If True, returns all the cases containing all attribute_values and in which attribute_values[i] was eventually followed by attribute_values[i + 1] - If False, returns all the cases not containing all attribute_values, or in which an instance of attribute_values[i] was not eventually followed by an instance of attribute_values[i + 1]

Returns
