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…]
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.
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…]
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…]

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 In this release, the thresholds have been replaced by a single noise level which can be set to 0, 1, 2, …, 19, or 20 percent.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…]
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…]
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…]
Today, I have released version 6.9.44 of the LogSkeleton package. The new features in this release are: The Always After, Always Before, and Never Together constraints now use the Declare names: Response, Precedence, and Not Co-existence. The Response, Precedence, and Not Co-existence constraints now are visualized like in Declare, where Not Co-existence uses two orthogonal … [Read more…]
