8. The project Title: Mapping Data Sources to XES in a Generic Way Goal: Create an application prototype that helps the user to define a mapping between a data source and the elements in the event log format XES. This application should also be able to produce the log in the XES format according to this mapping. / Architecture of Information Systems Group

10. Process Mining – A Brief Introduction • Extract knowledge from event logs, e.g.: • Business processes • Business rules • Social networks • Classes of Process Mining: • Discovery (construct models) • Conformance (verify models or rules) • Extensions (improve or enrich models) / Architecture of Information Systems Group

11. Process Mining – The Process / Architecture of Information Systems Group

14. Conversion Aspects – Convergence The same activity is executed on multiple cases at once. Case 4 Create events 13 Cases 4 Cases 4 Create events / Architecture of Information Systems Group

15. Conversion Aspects – New Conversion / Architecture of Information Systems Group

16. Conversion Aspects – Divergence For one case the same activity is executed multiple times. Case 4 Cases 4 Create events 9 Deliveries / Architecture of Information Systems Group

17. Conclusion • It is possible to create a generic conversion tool for event logs • Generic enough for many situations • Allows conversion definition without programming • Improves readability for process miner and domain expert • Guides in the conversion definition • Conversion definition influences analysis results • Points of improvement • Visualization • Performance • Usability / Architecture of Information Systems Group

18. Questions and Discussion Any questions? / Architecture of Information Systems Group

19. XES – The New Event Log Format • General event log format • Simple • Flexible • Extensible • Expressive • Conversion from and to MXML supported • Implemented by Christian W. Günther / Architecture of Information Systems Group
