Hi everyone!
Can you advice me plugin for conformance checking (logs + Petri Net)... I need just a values, that mean a Quality, Simplicity, Precision and Generalization.
Thanks!

    Hi sitesv,

    In ProM 6, there is a plugin called "Replay Log on Petri Net for Conformance Checking" that provides Fitness value as mentioned in [1,2] (depends on whether you use algorithm that consider proper termination/not). Furthermore, the result of the plugin (PNRepResult object) can be used as an input to plugin "Measure Precision/Generalization" to provide precision and generalization values as mentioned in [2]. 

    For a more robust precision analysis, I suggest to install ProM nightly build and use plugin "Check Precision based on Align-ETConformance" [3]. Otherwise, you can also use its predecessor plugin "Check Conformance using ETConformance" [4] which yields the same results under assumption that there is no silent/duplicate transitions.

    To measure simplicity, I suggest to use plugin "Conformance Checker" in ProM 5. 

    Cheers,
    Arya

  • Good day! 
    What plug-in can calculate classic fitness metric? not using cost-based approach

    In this archive placed log file and PetriNet file...
    Trying to replay this log on Petri net by using a plug-in "Replay the log on petri net for conformance analysis" for fitness metric.
    But i receive a bad results... I don't see a final event in tables (green, yellow,pink ... vertical lines).
    Using a settings by default...

    What i do wrong? May be i not correctly construct the logs?

  • Hi sitesv!

    The problem here is the log. Each event must have at least a "concept:name" attribute. Typically, the attribute is used as the name of activity represented by the event. The following tags are example of an attribute of an event tag:

    <event>
    <string key="org:resource" value="HR"/>
    <date key="time:timestamp" value="2010-10-08T00:00:00.000+02:00"/>
    <string key="lifecycle:transition" value="complete"/>
    <string key="concept:name" value="activity name"/> 
    </event>
    ...

    For further details on log formats, please refer to http://www.xes-standard.org/
