ProM.win.tue.nl offline

JBuijs — Mon, 17 Oct 2011 03:44:00 -0400

Dear all,

Today’s
ProM meeting is herewith cancelled.

This
morning, I’ve put prom.win.tue.nl off-line. At some point in time, we need to
let go of this server, and today seemed like a good time. I’ve fixed broken
links in the Process Mining site (www.processmining.org),
the AIS site (www.win.tue.nl/ais), and the
IS site (www.win.tue.nl/is).
Nevertheless, there still could be some links to prom.win.tue.nl somewhere. For
this reason, I include a redirection table below (addresses on the left-hand
side should be replaced by addresses on the right-hand side):

http://prom.win.tue.nl/research/wiki
-> http://www.processmining.org

http://prom.win.tue.nl/tools/prom6
-> http://www.promtools.org/prom6

http://prom.win.tue.nl/tools/prom
-> http://www.promtools.org/prom5

Cheers,

Eric.

UPD: Moving the forum - forum closed on Friday 18-3 afternoon

JBuijs — Thu, 24 Feb 2011 03:19:29 -0500

Not only the SVN, trac and website are moving away from prom.win.tue.nl but also the forum will move.
Therefore, the forum will temporally close on Friday 18 March 2011 from (roughly) 15:00 till 18:00 GMT+1.

After that you will be forwarded automatically to the new forum location.

Sorry for any inconvenience.

[ProM-developers] Serialization

JBuijs — Tue, 12 Apr 2011 03:24:37 -0400

Dear all,

From now, it is possible to switch off serialization in the ProM ini file. Just add the following lines:

#
# Indicate whether or not ProM should serialize the
# workspace. If switched off, the last serialized
# workspace will be loaded on each start
DO_SERIALIZATION = false

If serialization is switched off, the last serialized workspace will be loaded on every start. This is helpful for debugging purposes.

Please keep in mind that it is necessary to test your work with serialization switched on.

Cheers,
Boudewijn

Question about the graph type of the alpha algorithm

JBuijs — Mon, 22 Nov 2010 10:44:08 -0500

On behalf of Tahereh Sadat Mousavi who asked the following question to Eric Verbeek:

Dear Eric.,

I have a beginner question about Petri Net models that are output
of Alpha algorithm, are they directed multi graphs ? I think , output of
Alpha algorithm can be a cyclic graph ,is it true?

Do you know an algorithm that can find all paths form start node to end node in
these graphs?

Thank you very much in advance

With best regard

How do I create a mapping in XESame from .csv to XES?

JBuijs — Fri, 15 Oct 2010 06:35:40 -0400

From
http://prom.win.tue.nl/forum/index.php?p=/discussion/comment/71/#Comment_71
Where this question was asked:

---------------------------------------
The certainly helped me.

one more query regarding generating .xes / .mxml file of my own data source.

I have a .csv file. how do i generate the ".mappings" for this file?

so that, using that i can generate .xes from XESame.

I tried to go through your thesis report. but i didnt find the explicit steps for generation of mappings.

---
Thanks.
Narayan.

-------------------------------------

Answer:
A definition can be made in the definition workspace (middle tab on the top). Here you see a tree structure with different elements of the mapping.
How to define a mapping using this tree structure and what to enter in each field can be read in my Master's thesis, mainly in Chapter 5, Section 5.3.2. More complex examples are discussed in Chapter 6 which will also help you to understand the definition of the mapping.
See http://prom.win.tue.nl/research/wiki/_media/xesame/xesma_thesis_final.pdf

Good luck Narayan!

[ProM-developers] ProM and SVN 1.7

JBuijs — Thu, 05 Jan 2012 06:24:36 -0500

Dear all,

For the time being, it is not a good idea to use SVN 1.7 in combination with ProM 6. Therefore, please stick to SVN 1.6.

All ProM packages use a folder external called “stdlib” that links to the lib folder of the ProM framework. As a result, all necessary files for the framework are included in every package. So far, so good. However, the four ProM jar files (ProM-Framework.jar, ProM-Contexts,jar, ProM-Models.jar, and ProM-Plugins.jar) are included by means of four file externals in this stdlib folder. SVN 1.6 simply adds these four jar files to the stdlib folder (which seems to be an undocumented feature), but SVN 1.7 forbids this. Hence, you will not be able to check-out any ProM 6 package if you’re using SVN 1.7.

Cheers,

Eric.

[ProM-developers] CFP Special Session on Process Mining at IEEE Congress on Evolutionary Computation

JBuijs — Fri, 25 Nov 2011 02:33:22 -0500

Moe Wynn send this message to the ProM-Developers mailing list:

CALL FOR PAPERS
The IEEE Task Force on Process Mining (www.win.tue.nl/ieeetfpm) is organizing a special session at the 2012 IEEE World Congress on Computational Intelligence/ IEEE Congress on Evolutionary Computation (IEEE CEC/WCCI 2012). The goal of this special session is to join experts in the area of process mining to present new techniques and applications. Therefore, submissions of papers on new process mining techniques, computational intelligence applications of process mining, business intelligence, automated business process discovery, conformance checking, process intelligence, etc., are welcome. See http://processminingcec2012.wordpress.com/ for more details on the special session. See http://www.ieee-wcci2012.org/ieee-wcci2012/ for detailed submission information.
Process mining is a relative young research discipline that sits between computational intelligence and data mining on one hand, and process modeling and analysis on the other hand. The idea of process mining is to discover, monitor and improve real processes (not assumed processes) by extracting knowledge from event logs readily available in today's systems. Process mining provides an important bridge between data mining and business process modeling and analysis. Process mining research started in the late nineties. At that time there was little event data available and the process mining techniques were extremely naive and hence unusable. Over the last decade, event data has become readily available and process mining techniques have matured. Moreover, process mining algorithms have been implemented in various academic and commercial systems. Today, there is an active group of researchers working on process mining and it has become one of the "hot topics" in BPM research. Moreover, there is a huge interest from industry in process mining. More and more software vendors started adding process mining functionality to their tools. Furthermore, the diverse range of computational intelligence approaches and methodologies are well suited to approaches combining process mining and other computational intelligence adaptive business systems.

Process Mining book

JBuijs — Wed, 20 Apr 2011 06:30:00 -0400

Prof.dr.ir. W.M.P. van der Aalst just send the following e-mail to the ProM users mailing list:

Slides and Event Logs supporting the new book "Process Mining: Discovery, Conformance, and Enhancement of Business Processes"

http://www.processmining.org/book/ ;

Process mining provides a new means to improve processes in a variety of application domains. Driven by the omnipresence of event data and the limitations of Business Process Management (BPM) and Business Intelligence (BI) approaches, a new discipline has emerged that builds on classical process model-driven approaches and data mining. During the last decade, breakthroughs have been realized that make it possible the automatically discover business processes from event data present in information systems ranging from ERP systems (e.g. SAP and Oracle) and E-business applications to hospital information systems and high-tech production systems. Process mining can also be used for conformance checking in the context of auditing, compliance, and governance. Moreover, by projecting event data onto discovered models, business processes can be improved in terms of costs, time, and quality.

The book "Process Mining: Discovery, Conformance, and Enhancement of Business Processes" (Springer, http://springer.com/978-3-642-19344-6, ISBN 978-3-642-19344-6) by Wil van der Aalst is the first book on Process Mining. It collects the state-of-the-art results available in publications, software and best practices. To support the book a website http://www.processmining.org/book/ has been created containing slides, event logs, and models. The slides can be used for presentations, e.g., for university seminars to discuss the emerging topic of process mining and for training IT and business consultants to provide services based on process mining. Many of the event logs mentioned in the book are available via http://www.processmining.org/book/. The open-source software ProM (http://www.promtools.org/prom6/) and other tools supporting the XES or MXML format can be used to discover process models from these example logs. Also models have been included to experiment with conformance checking (pinpoint discrepancies between event log and model) and other types of analysis.

For more information on process mining visit www.processmining.org. For more information on the new process mining book see http://springer.com/978-3-642-19344-6. People of organizations that have the proper SpringerLink subscription can download the book from http://www.springerlink.com/content/978-3-642-19344-6.

[ProM-developers] Changes to XAttribute 'equals(object )' method in OpenXES

JBuijs — Thu, 14 Apr 2011 02:44:13 -0400

Yesterday, Danny van Heumen send around the following message on the ProM Developers mailing list:

Dear all,

As of today, the equality of an XAttribute and its specializations (XAttributeLiteral, XAttributeBoolean, XAttributeDiscrete, XAttributeContinuous and XAttributeTimestamp) have been modified. The new implementation is more in line with what one would expect of this method: two attributes are considered equivalent if key, value type and value all are equivalent in both attributes.

Previously, when we would compare two XAttribute instances, it would only test whether or not the key of both instances is equal. The value type and value of the attribute would be ignored.
As of now, when we compare two XAttribute instances, key, value type and value have to all be equivalent in order for two XAttribute instances to be considered equal.

Note that given the large amount of ProM packages already present and the nature of the 'equals(...)' method, i.e. 'equals(...)' may also be used (under the hood) by algorithms and data structures, we cannot easily test if this change breaks any of the existing ProM packages. So, if anyone notices a sudden breakage it might be related to this change, although there should only be such a problem if your packages uses XAttribute's 'equals(...)' method for comparing one XAttribute to another.

If the old behavior is required, you can trivially achieve this with the XAttribute's 'getKey()' method which returns the key and those keys can then be compared.

Best regards,

Danny

[ProM-developers] Test Cases for ProM

JBuijs — Thu, 07 Apr 2011 05:34:40 -0400

Last Monday Dirk Fahland presented a way to test your ProM plug-ins. He send around the following mail to the ProM developers list:

I briefly presented how I have set up test cases
for my ProM plugins. I just finished Tutorial in the ProM wiki describing what
you have to do, to use test cases for your own plugins. You can find the
tutorial at

https://svn.win.tue.nl/trac/prom/wiki/TestCases

I am aware that we are not providing you a comfortable
push button technology. Things are rough at the moment, and we need your
feedback to make things more accessible. Please read the tutorial and start
writing your own tests. Whenever you have questions or run into problems,
please approach me.

[ProM-developers] Classifiers

JBuijs — Mon, 04 Apr 2011 03:26:40 -0400

This morning Eric send the following message to the ProM Developers mailing list:

Dear all,

This weekend, we noticed that some plug-ins ‘massage’ the result of classifier to obtain the result from a different classifier. For example, if the result of the concept name classifier would be “X”, then “X+complete” would be a valid result from the standard classifier. *Please do not do this*. If you need to know the results of some classifier on some event, run the classifier on the event, and do not start guessing around with the results of other classifiers. For example, if the result of the standard classifier is “X”, then *do not assume* that “X”is of the form “Y+Z” and do not start looking for the Y –part to obtain the result of the name classifier. First of all, we just might change the “+” into some other string, second, we just might swap “Y+Z” to “Z+Y”, and third, Y itself may contain several instances of “+” which would result in strange results.

Please note that it is not hard to obtain the results from a classifier, as the class XLogInfoImpl has a number of classifiers predefined:
-   XLogInfoImpl.STANDARD_CLASSIFIER(event)
-   XLogInfoImpl.NAME_CLASSIFIER(event)
-   XLogInfoImpl.RESOURCE_CLASSIFIER(event)
-   XLogInfoImpl.LIFE_CYCLE_CLASSIFIER(event)

If you know that your plug-in relies on assumptions as mentioned above, please change your plug-in accordingly.

Finally, please note that at 12:30 we have another ProM lunch today. Dirk Fahland will introduce us to the way he has his plug-ins tested by the Hudson server.

Cheers,

Eric.

[ProM-developers] New version of ProM framework: Update build path!

JBuijs — Thu, 31 Mar 2011 07:48:42 -0400

Eric Verbeek just send this message on the ProM Developers mailing list:

Dear all,

I’ve just released a new version of the ProM framework, one
that contains functionality to export Petri nets, transitions system, …
(directed graphs, in general) to different output formats (eps, pdf, …). This
new functionality needs a number of new external jar files. Hence, if you
update your package, you will have to update your build path accordingly (in
the stdlib folder there will be some new jar files, please add them to the
build path).

Cheers,

Eric.

Unknown SVN host when checking out ProM/XESame

JBuijs — Wed, 02 Feb 2011 06:16:47 -0500

I just received this question via e-mail:

Dear Joos

My name is ..., im doing my master thesis using prom, i was trying to access to XESame, which will be really helpful for obtaining logs from a database, but i get the following mistake on my eclipse console :

No such host is known.
svn: Unknown hostname 'prom.win.tue.nl'

Has the host server changed?

[ProM-developers] Links

JBuijs — Tue, 01 Feb 2011 03:04:59 -0500

Eric Verbeek send the following message on the ProM Developers mailing list this morning:

Dear all,

As from now on, please use the new ProM 6 SVN repository, which is located at https://svn.win.tue.nl/repos/prom . As with the old repository, the new repository also comes with a trac site, which can be found at https://svn.win.tue.nl/trac/prom . Note, however, that there is still an issue with creating tickets on the new trac site. BCF still needs to solve this.

Furthermore, the new Hudson server (http://svishudson.win.tue.nl:8080) is now operational. This server checks the new repository for changes, and will perform builds whenever necessary. As mentioned yesterday, we now have two classes of packages: stable packages and non-stable packages. Whenever a change is detected in a non-stable package, a build will be performed on the package, and any errors will be communicated to the author of the change. Whenever a change is detected in a stable package, builds will be performed for the package and any downstream package (that is, any package that uses the package in its packagelib folder). Again, any errors will be communicated to the author of the change, and it’s the responsibility of this author to fix any problems (which includes problems in downstream packages). Note that we assume that stable package are free of errors themselves, hence, the error in a downstream package should be caused by the upstream change. If you think your non-stable package has become stable now, please let me know so we can change its status.

For the Hudson server to communicate the errors to the authors, it is important that you register your SVN account on the server. To do so, please go to the server, select the “Sign up” link in the upper right corner, provide your credentials, and select the “Sign up” button. Please provide the same username as you have in the SVN repository, and provide a valid e-mail address. Errors will be communicated by the server to the e-mail address provided, so this is kind of important.

Finally, let me know if you think you lack credentials anywhere in the repository, trac, or Hudson. Almost everything can be fixed, as long as we’re aware of it.

Cheers,

Eric.

Update Joos: corrected link to Hudson server

XESame with single table and non-unique IDs

JBuijs — Tue, 25 Jan 2011 06:15:39 -0500

User 'Pachf' asked the following questions in this topic:

I saw the order example for XESAME, I opened it and it was ok
(visualization also), but I have a question: it is possible to create a
mapping for only one data table (no multi table with relations)?

For example if we have a structure in a csv file:

ID;date_of_order;date_of_delivery;product

1;01-01-2011;03-01-2011;A

1;01-01-2011;04-01-2011;A

2;01-01-2011;04-01-2011;A

3;01-01-2011;04-01-2011;B

4;01-01-2011;04-01-2011;A

...

It
XESAME mapping works with non-uniqe ID, if I have only one ID for order
and delivery (and product delivery are in two phase; e.g. product A
first with ID 1 then the rest also with ID 1 but at the same day)? So I
have full processes and I want to define ordering as trace and order,
deliver as two events.

Or it works only with more tables (order, delivery, etc.) and links between them?

Thanks

Mining subprocesses

JBuijs — Fri, 17 Dec 2010 05:36:02 -0500

Pieter van Gorp asked the following questions on the ProM mailing lists on December 13:

Hi all,
can somebody please provide a state-of-the-art w.r.t. process mining with support for subprocesses?

A quick google learned me that subprocesses are mentioned in http://prom.win.tue.nl/research/wiki/_media/publications/jcbose2009b.pdf
but I wonder which mining plugins support the mining of subprocess definitions ans calls. I also wonder in which documented case studies such plugins have been evaluated so far.

Sincerely,
Pieter Van Gorp

UITopia sources

Part of a conversation between Andrea Burattin and Boudewijn van Dongen in which Andrea asked:

...(part of conversation)...
I think I can solve most of the problems if some specific
documentation is available or if I can find the source code of the
user interface. I think that I'm talking about the Uitopia component,
but I can't find its source code. Can you give me some pointer to the
sources?

Missing features (objects with long names cannot be deleted)

JBuijs — Mon, 13 Dec 2010 08:55:21 -0500

Part of a conversation between Andrea Burattin and Boudewijn van Dongen in which Andrea asked:

In the action tab, when there is an object with a long name (see
attached image), it is not possible to remove it from the current
input objects (the "X" button is not visible; and from the "Select
resource" dialog if I deselect the current object (with CTRL+click on
it) and then press "Select" the resource is still there).

(Note: the referred image is not attached to this discussion but the description is quite clear)

Strange behaviour - parameter matching of plug-ins

JBuijs — Mon, 13 Dec 2010 08:53:13 -0500

Part of a conversation between Andrea Burattin and Boudewijn van Dongen in which Andrea asked:

I have the AuthoredType PLGProcessCollection that extends
Vector. When I use it, the action tab matches also the
second parameter of Declare miner, that is just a Vector.

Call for actions

JBuijs — Mon, 13 Dec 2010 08:50:56 -0500

Part of a conversation between Andrea Burattin and Boudewijn van Dongen in which Andrea asked:

When I visualize the collection of logs I want to add a button for
"playing" a single log. The expected behaviour is the same of the ">"
button (with tooltip "Use resource") of the workspace, when a resource
is selected (that is to show the "Actions" tab with the given log as
"input object").

Add object into the workspace, from a non-plugin method

JBuijs — Mon, 13 Dec 2010 08:49:34 -0500

Part of a conversation between Andrea Burattin and Boudewijn van Dongen in which Andrea asked:

When I visualize the collection of logs I need to add a button for
"exporting" a log from the collection to the workspace. I have a
reference to the UIPluginContext but I have not succeeded in adding an
AuthoredType object into the workspace.

Remove objects from the workspace

JBuijs — Mon, 13 Dec 2010 08:47:41 -0500

Part of a conversation between Andrea Burattin and Boudewijn van Dongen in which Andrea asked:

I have two plugins: one for the generation of a single process

(AuthoredType PLGProcess) and one for the generation of collection of

processes (AuthoredType PLGProcessCollection). The latter repetitively

calls the former (with the method tryToFindOrConstructFirstObject of

the context). The problem is that each call of the "single process

generator" creates the objects into the workspace. Since I add all the

processes to the collection, is it possible to remove them from the

workspace?

DateTime format in XES and MXML event logs

JBuijs — Thu, 09 Dec 2010 10:31:55 -0500

Marco Montali e-mailed me today with the following question, which, I agree, might be of interest for the XES community.

The problem is twofold, and I think that both issues are of interest for the XES community.

The first issue is related to parsing logs containing timestamps in a format different than something like 2005-10-24T11:57:31.000+01:00.
In particular, both the XesXMLParser and the XMXMLParser are bound to this format, and I didn't found an easy way to set up a different format.
Looking into the APIs of OpenXES, I have found that both parsers rely on XsDateTimeConversion to parse timestamps. However, the XsDateTimeConversion object used for parsing is a protected member of the parsers, and therefore cannot be customized from the external world.
Indeed, XsDateTimeConversion understands only the format I have shown before (you can find this information at http://code.deckfour.org/xes/doc/org/deckfour/xes/util/XsDateTimeConversion.html).

In order to make it possible to customize the dateformat, I have therefore implemented an ugly patch, subclassing the parser and assigning inside the constructor a subclass of the XsDateTimeConversion, which now takes a dateformat as a parameter. You can find the implementation below.

However, there is still another issue related to Localization: by default, the SimpleDateFormat class is instantiated with the Locale of the running application. However, in the general case the Locale associated to the user who generated the log could be different than the Locale associated to the user who is importing and analyzing that log. If these two users are associated to different Locales, then setting up the right dateformat is not sufficient when timestamps contain not only numbers, but also textual information.

For example, Fabrizio was trying to parse a log where timestamps' months are represented with three letters ("Sep" for september). The parser didn't work, because the format was not recognized. Hence I implemented the patch described above, making it possible to pass to the parser a customized format (EEE MMM d HH:mm:ss z yyyy). But still the parser didn't work, because Fabrizio's Locale is "IT", and therefore the SimpleDateFormat didn't recognize "Sep" as a valid month (it expected "Set", because the italian version of "september" is "settembre").

When Fabrizio recognized this problem, it was easy to fix it (it sufficies to add the right Locale - Locale.ENGLISH) as a second parameter when constructing the SimpleDateFormat.
However, this means that the user who is importing the log MUST KNOW the Locale of the user who has generated it. It would be definitely better to automatically extract this information from the log.

Thanking you in advance for the attention,

Cheers

Marco

[ProM-developers] Moving models into packages

JBuijs — Tue, 07 Dec 2010 09:08:35 -0500

Eric Verbeek just send this message to the ProM-Developers mailing list:

Dear all,

In the next few days, we will copy the various models (Petri nets, transition systems, fuzzy models, EPCs, …) into separate packages. While doing so, we will update the dependencies in the repositories. Nevertheless, there could be ‘ glitches’, please let us know when you detect such a glitch, so we can fit it.

After everything has been copied, we will start removing the corresponding sources from the models project. In this stage, you might have to add jar files of other packages into your packagelib folders, as the support for these models will have been removed from the models project.

Until further notice, please do not make changes to the models (or accept the fact that you might have to redo your changes, of course).

Kind regards,

Eric.

[ProM-developers] Conversion to mxml

JBuijs — Fri, 05 Nov 2010 08:51:36 -0400

On Friday 5-11-2010, 10:03 CET the following message was posted on the prom developers mailinglist:

Good Morning Doctors,

I am an italian student of Politecnico of Torino
(Management Engineering).

I need your help for a conversion of a file Access to a
log file for ProM 5.2.

First, let me explain why : I am doing a relation about
your software ProM and the ideas and purposes inside the software (why exists
and why you create it...) ; a main part of this relation, which is in fact a
short thesis, consists in an application of the software with a simple example
and a simple database: a comparison between results with proM and other way
results.

So i need the software for a statistical analysis to
prove the accuracy of your software.

I downloaded your proM import framework and i tried to
convert my file, but my knowledge of Java 'language' is very bad and i can't
solve errors.

To go on, i need that someone could convert this file for
me.

I ask you if it is possible to have a converted and
tested version of the file, please.

I leave the file attached to this mail, if you gently
could help me.

Best Wishes,

Niccolò Milano
