PDC 2019: Award
Yesterday, I received the “Process Discovery Contest Award” for my winning submission to the Process Discovery Contest 2019. Many thanks to Massimiliano, Benoit, and Josep for organizing the contest. Next year, I will help them :-).

PDC 2019: Classified 898 out of 900 traces correctly
The nets I discovered for the Process Discovery Contest (PDC) 2019), classified 898 out of 900 correctly as fitting or non-fitting. Hence, I achieved with them a classification accuracy of 99.78%. Below, you’ll find all discovered nets. All nets are sound WF-nets. Both nets 9 and 10 classify a single trace wrongly. All nets were … [Read more…]
Screencast showing the use of the Log Skeleton Filter an Browser
This screencast shows how the Log Skeleton Filter an Browser is used to ‘discover’ a sound WF net from training log 4 of the Process Discovery Challenge 2019.

The Log Skeleton Filter and Browser demo has been accepted for the ICPM 2019 conference.
New visualizer plug-in: Log Skeleton Visualizer
Version 6.9.91 of the LogSkeleton package includes a new log visualizer plug-in that allows the user to use any classifier for the log skeletons. So far, the log skeletons were restricted to the “concept:name” attribute, but this restriction has now been lifted. The screenshot below shows the result of using the “org:resource” classifier on the … [Read more…]
Updated documentation for LogSkeleton package
Version 6.9.86 The documentation now includes a description of the new browsing options, including the noise level, and the plug-in that partitions a log into sublogs by clustering the traces on their support sets. As an example, the figure above shows the default log skeleton for the first sublog of the PDC 2017 training log … [Read more…]
New Features: Not Response, Not Precedence
In the picture above: |> is always followed by q.0 and e, and is never preceded by a or u. a is always preceded by |>, does never occur with u, and is always followed by q.0 and e. u is always preceded by |>, does never occur with a, and is always followed by … [Read more…]
New Feature: Noise level, also affects equivalence relation
Today, I have released version 6.9.62 of the LogSkeleton package. In this release, the thresholds have been replaced by a single noise level which can be set to 0, 1, 2, …, 19, or 20 percent. Furthermore, the equivalence relation (the ‘colors’ of the activities) now also takes this noise into account. As an example, … [Read more…]
New Features: Threshold for Not Co-Existence, new colors
Today, I have released version 6.9.56 of the LogSkeleton package. The new features in this release are: A threshold for the not co-existence constraint, like the threshold for the reponse and precedence constraints. Uses blue for response and precedence constraints and red for not co-existence constraints. Fixed the import and export on the thresholds. The … [Read more…]
New Features: Almost-always, Edge Colors, and Head/Tail Labels
Today, I have released version 6.9.51 of the LogSkeleton package. The new features in this release are: The option to use “Almost-always” relations. Using a slider, the user can set a threshold for this “Almost”, which ranges from 80 (holds for 80% percent of all occurrences of the activity) to 100 (holds for all occurrences). … [Read more…]
