pm4py.algo.transformation.ocel.graphs.object_cobirth_graph module

pm4py.algo.transformation.ocel.graphs.object_cobirth_graph.apply(ocel: OCEL, parameters: Dict[Any, Any] | None = None) → Set[Tuple[str, str]]

Calculates the object cobirth graph. This is calculated as follows:

• Given the set of objects related to an event, they belong to two different categories:

  • The “seen” objects (they have appeared in some earlier event)

  • The “unseen” objects (they appear for the first time in the current event).

• Every “unseen” object is connected to every “unseen” object

Parameters:

• ocel – Object-centric event log

• parameters – Parameters of the algorithm

Returns:

Object cobirth graph (undirected)

Return type:

object_cobirth_graph
