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