Event logs

To be able to apply process mining techniques it is essential to extract event logs from data sources (e.g., databases, transaction logs, audit trails, etc.). The target formats supported by ProM are MXML (Mining eXtensible Markup Language) and XES (eXtensible Event Stream). XES was selected by the IEEE Task Force on Process Mining as the standard format for logging events.

There are several tools to extract MXML or XES logs from various data sources. See for example:

Once the relevant data has been located, the extraction and conversion is fairly straighforward. The challenge is to select event data related to the questions an organization has.

For people new to the field, it is interesting to experiment with various data sets. Therefore, this website contains pointers to various example datasets:
