mining method described here has been integrated into
the framework ProM,
which supports a variety of tools for process mining.
In particular, we developed two plugins:
DWS mining is a mining
plugin that implements the whole process mining approach: it allows to build
and browse a tree of workflow models for a given log - actually
HeuristicMining algorithm provided with ProM is used to derive each
model in the tree.
DWS analysis is an analysis plugin that allows to
analyse a given log in a
interactive way: it allows to discover a set of features (discriminant rules) in
the log, as well as to partition its traces into a set of clusters according
to these features.
The main parameters that can be set
when using the plugins are:
the maximum number and the maximum
lenght of the features
the two thresholds sigma and
gamma (shortly described in Introduction) used
when searching for features
the maximum number of clusters that
can be produced by a refinement step
the maximum number refinements that
can be performed (only for the mining plugin)
Both plugins obviously require
the installation of ProM framework, as well as
a suitable Java Virtual Machine (version 1.4 or later).
In order to install ProM,
please refer to the
ProcessMining web site (section "Tools" ).
After installing ProM, please follow the steps below in
order to install both plugins:
Download the files DisjunctiveWS.jar and
containing the software and the associated documentation, respectively.
denote the folder where ProM has been installed.
Put the jar file in the folder
Now you need to modify the .ini
file that are contained in the folder ProMDir
as explained below, in order to make the framework ProM know about the existence
of the two pugins.
Open the file analyses.ini
(in ProMDir) with a text editor (e.g., TexPad).
This file contains a list of the analysis plugins in the framework: a line
of the form PluginName=ClassName appears for each of them. Please
note that the PluginName acts as an unique identifier for plugins
Append to the list the line S=org.processmining.analysis.dws.DWSAnalysis.
Please check whether the symbol S has already been used it the
list: in this case a different one, that does not appear in the list,
must be chosen.
Open the mining.ini file
(in ProMDir) with a text editor.
This file contains a list of all known mining plugins, with one line
PluginName=ClassName for each of them.
Append to the list the line
I=org.processmining.mining.dwsmining.DWSMiner. Please make sure
that the PluginName chosen does not already appear in the list.
Finally, open the ProM.bat
(in ProMDir) with a text editor and
append to the classpath list the line set CLASSPATH=%CLASSPATH%;.\lib\plugins\DisjunctiveWS.jar.
GUI you can make use of both plugins.
notice that two novel entries appear in the list of process mining and analyis
Workflow Scheme Algorithm, which can be accessed choosing the operation
Open New Log from the menu Mining;
Analysis, which can be applied to any workflow model mined with ProM
(including those that appear in a tree of models)
Notice that currently both plugins do not cope with the presence of loops in the
In any case, if the plugins do not work properly, please ask to Antonella for
