Class LoglessAlphaMiner

java.lang.Object

org.processmining.hadoop.AlphaMiner.algorithms.LoglessAlphaMiner

public class LoglessAlphaMiner
extends java.lang.Object

Class implementing the Alpha Miner The Miner uses as input a directly-follows graph (DFG) and applied the Alpha Miner. The implementation is inspired in the one in the Alpha Miner ProM plugin TODO: Add length-one loops support

Mine a Petri Net from a Graph using the Alpha algorithm

Parameters:

dfg - Directly-follows graph

Returns:

Mined PetriNet

Throws:

java.util.concurrent.ExecutionException

java.lang.InterruptedException

getCausalRelations

public java.util.HashMap<java.lang.String,java.util.Set<java.lang.String>> getCausalRelations(HadoopGraph dfg)

Returns a map with the causal relations in the graph. The key of the map is the predecessor and the set of values are the successors

Parameters:

dfg - Directly-follows graph

Returns:

Map with the causal relations in the graph
