Colloquium IS (July 6, 2018) – Discovering Anomalous Frequent Patterns from Event Logs

Dear all,

We are pleased to invite you to our next Colloquium IS that will take place on Friday,

July 6, 2018, 16:00 – 17:00 (Paviljoen K.16).

Speaker: dr. Laura Genga

Title: Discovering Anomalous Frequent Patterns from Event Logs


Conformance checking allows organizations to compare process executions recorded by the IT system against a process model representing the normative behavior. Most of the existing techniques, however, are only able to pinpoint where individual process executions deviate from the normative behavior, without considering neither possible correlations among occurred deviations nor their frequency. Moreover, possible parallelisms among process activities are usually neglected,

which can lead to inaccurate diagnostics. In this talk, I will introduce an approach to extract anomalous frequent patterns from historical logging data. The extracted patterns can exhibit parallel behaviors and correlate recurrent deviations that have occurred in possibly different portions of the process, thus providing the analysts with a valuable aid in investigating nonconforming behaviors. The approach has been evaluated using both synthetic and real-life logs.
