org.processmining.nlplogutils.algorithms.fodina.FodinaContextCreator

All Implemented Interfaces:

ContextCreator

public class FodinaContextCreator
extends java.lang.Object
implements ContextCreator

Simple duplication strategy based on the paper: "Fodina: A robust and flexible heuristic process discovery technique" by Seppe K.L.M. vanden Broucke, , Jochen De Weerdt The point is to group contexts (1 look ahead and 1 back) wherever at least one neighbor is shared. quote: " The set of contexts for activity a is then equal to {(start, a, b),(start, a, c), (c, a, d), (b, a, d), (c, a, e), (b, a, e), (e, a, end), (d, a, end)}. The set of grouped contexts is constructed so that the local contexts of a are separated so that they do not overlap with one another: {{(start, a, b), (start, a, c)}, {(c, a, d), (b, a, d), (c, a, e), (b, a, e)}, {(e, a, end),(d, a, end)}}, representing three duplicate tasks." http://www.sciencedirect.com/science/article/pii/S0167923617300647 Created by andreas on 5/22/17.

Method Detail

setup

public void setup(org.deckfour.xes.model.XLog log,
                  org.deckfour.xes.classification.XEventClasses classes,
                  java.lang.String origLabel,
                  long seed)

Specified by:

setup in interface ContextCreator

Parameters:

log - the log which is processed

classes - the event classes that appear in the log

origLabel - the event label for the class that will be disambiguated.

seed - the seed for any random stuff that is happening inside the context creator

addToContext

public void addToContext(int traceId,
                         int eventId,
                         java.util.List<org.processmining.framework.util.Pair<org.deckfour.xes.classification.XEventClass,java.lang.Double>> contextBefore,
                         java.util.List<org.processmining.framework.util.Pair<org.deckfour.xes.classification.XEventClass,java.lang.Double>> contextAfter)

Specified by:

addToContext in interface ContextCreator

Parameters:

traceId - The id of the trace in the log (log.get(traceId) would return the )

contextBefore - The context before the current event

contextAfter - The context after the current event

getModifications

public java.util.List<Modification> getModifications()

Description copied from interface: ContextCreator

We can assume that all the events were added ContextCreator.addToContext(int, int, List, List) before.

Specified by:

getModifications in interface ContextCreator
