pm4py.algo.transformation.ocel.graphs.object_cobirth_graph.apply(ocel: OCEL, parameters: Optional[Dict[Any, Any]] = 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

Object cobirth graph (undirected)

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

Calculates the object codeath graph.

This is calculated like the object cobirth graph, but visiting the list of events in the reverse order.

Parameters#

ocel

Object-centric event log

parameters

Parameters of the algorithm

Returns#

object_codeath_graph

Object codeath graph (undirected)

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

Calculates the object descendant 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 “seen” object is connected to every “unseen” object.

Parameters#

ocel

Object-centric event log

parameters

Parameters of the algorithm

Returns#

object_descendant_graph

Object descendant graph (directed)

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

Calculates the object descendants graph. Two objects o1 and o2, both related to an event e, are connected if: - e is the last event of the lifecycle of o1 - e is the first event of the lifecycle of o2

Parameters#

ocel

Object-centric event log

parameters

Parameters of the algorithm

Returns#

object_inheritance_graph

Object inheritance graph (directed)
