class pm4py.algo.transformation.log_to_interval_tree.variants.open_paths.Parameters(value)[source]#

Bases: Enum

An enumeration.

START_TIMESTAMP_KEY = 'pm4py:param:start_timestamp_key'#
TIMESTAMP_KEY = 'pm4py:param:timestamp_key'#
ACTIVITY_KEY = 'pm4py:param:activity_key'#
EPSILON = 'epsilon'#
FILTER_ACTIVITY_COUPLE = 'filter_activity_couple'#
pm4py.algo.transformation.log_to_interval_tree.variants.open_paths.log_to_intervals(log: Union[EventLog, DataFrame], parameters: Optional[Dict[Any, Any]] = None) List[List[Any]][source]#

Transforms the event log to a list of intervals that are the directly-follows paths in the log (open at the complete timestamp of the source event, and closed at the start timestamp of the target event).

Parameters#

log

Event log

parameters

Parameters of the algorithm, including: - Parameters.ACTIVITY_KEY => the attribute to be used as activity (default: xes_constants.DEFAULT_NAME_KEY) - Parameters.START_TIMESTAMP_KEY => the attribute to be used as start timestamp (default: xes_constants.DEFAULT_TIMESTAMP_KEY) - Parameters.TIMESTAMP_KEY => the attribute to be used as completion timestamp (default: xes_constants.DEFAULT_TIMESTAMP_KEY) - Parameters.EPSILON => the small gap that is removed from the timestamp of the source event and added to the

timestamp of the target event to make interval querying possible

  • Parameters.FILTER_ACTIVITY_COUPLE => (optional) keeps only the paths between the specified tuple of two activities.

Returns#

tree

Interval tree object (which can be queried at a given timestamp, or range of timestamps)

pm4py.algo.transformation.log_to_interval_tree.variants.open_paths.interval_to_tree(intervals: List[List[Any]], parameters: Optional[Dict[Any, Any]] = None) IntervalTree[source]#

Internal methods to convert the obtained intervals to the eventual IntervalTree

pm4py.algo.transformation.log_to_interval_tree.variants.open_paths.apply(log: Union[EventLog, DataFrame], parameters: Optional[Dict[Any, Any]] = None) IntervalTree[source]#

Transforms the event log to an interval tree in which the intervals are the directly-follows paths in the log (open at the complete timestamp of the source event, and closed at the start timestamp of the target event), and having as associated data the source and the target event.

Parameters#

log

Event log

parameters

Parameters of the algorithm, including: - Parameters.ACTIVITY_KEY => the attribute to be used as activity (default: xes_constants.DEFAULT_NAME_KEY) - Parameters.START_TIMESTAMP_KEY => the attribute to be used as start timestamp (default: xes_constants.DEFAULT_TIMESTAMP_KEY) - Parameters.TIMESTAMP_KEY => the attribute to be used as completion timestamp (default: xes_constants.DEFAULT_TIMESTAMP_KEY) - Parameters.EPSILON => the small gap that is removed from the timestamp of the source event and added to the

timestamp of the target event to make interval querying possible

  • Parameters.FILTER_ACTIVITY_COUPLE => (optional) keeps only the paths between the specified tuple of two activities.

Returns#

tree

Interval tree object (which can be queried at a given timestamp, or range of timestamps)
