ELEPM

ELEPM (Event Log Extractor Process Mining) is an extension of ELE framework to provide process mining functionalities. ELE is intended to provide developers and non-expert users with a powerful tool capable of extract event logs in XES format to ease process mining tasks. ELEPM provides such process mining facilities by means of some external frameworks such as ProM or Inductive Miner.

Case study

Please refer to ELE to check the whole case study. Bellow only the Test case C is shown.

In order to obtain the Petri net, first of all it is necessary to define the extraction as specified in ELE.

val xlog = 
 extract(
   define trace id("gticode"),
   define trace event(
     activity = "incidences.incidencetype",
     criteria = orderBy(t"start_date" -> toDate("MM/dd/yyyy HH:mm:ss")),
     timestamp = t"start_date" -> toDate("MM/dd/yyyy HH:mm:ss"),
     resource = t"incidencecode"
   )
 ) from "datasets/aircraft_dataset_anonymized.json"

Now, it is possible to obtain the Petri net by using the function petrinet. With the methods save and show, it is possible to save the Petri net in a text file and show a graph which represents it.

val petri = petrinet(xlog)

petri save("output/petrinet.txt")
petri show

Running the case study

The implementation has been carried out in a Scala object located at es.us.idea.ele.XesUtility. It can be executed by following the following steps:

1. Clone this repository

https://github.com/IDEA-Research-Group/ELEPM.git cd ADT

2. Execute the class es.us.idea.elepm.Utility

Using this framework in your project

In order to use this framework in a project, you need to import the following Maven dependency:

<dependency>

You will need the following imports to work with this tool:

1. The ELE DSL.

import es.us.idea.ele.xes.dsl.implicits._

2. The functions to perform process mining

import es.us.idea.elepm.pm.functions._

2. The transformation functions from the data-chameleon framework. It enables to transform fields and to specify the criteria to create the event logs..

import es.us.idea.adt.data.chameleon.internal.dtfs._

3. The DSL from the data-chameleon framework. It is usefull to use the transformation functions together with ELE.

import es.us.idea.adt.data.chameleon.dsl.implicits._
