 +===== Abstract =====
 +
 +Contemporary workflow management
 +systems are driven by explicit process
 +models, i.e., a completely specified workflow
 +design is required in order to enact a given
 +workflow process. Creating a workflow
 +design is a complicated time-consuming
 +process and typically there are discrepancies
 +between the actual workflow processes and
 +the processes as perceived by the
 +management. Therefore, we propose a
 +technique for rediscovering workflow models.
 +This technique uses workflow logs to
 +discover the workflow process as it is actually
 +being executed. The workflow log contains
 +information about events taking place. We
 +assume that these events are totally ordered
 +and each event refers to one task being
 +executed for a single case. This information
 +can easily be extracted from transactional
 +information systems (e.g., Enterprise
 +Resource Planning systems such as SAP and
 +Baan). The rediscovering technique proposed
 +in this paper can deal with noise and can also
 +be used to validate workflow processes by
 +uncovering and measuring the discrepancies
 +between prescriptive models and actual
 +process executions.
