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.

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)

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
