    abstract = {Modern enterprises increasingly use the workflow paradigm to prescribe how
      business processes should be performed. Processes are typically modeled as
      annotated activity graphs. We present an approach for a system that constructs
      process models from logs of past, unstructured executions of the given process.
      The graph so produced conforms to the dependencies and past executions present
      in the log. By providing models that capture the previous executions of the
      process, this technique allows easier introduction of a workflow system and
      evaluation and evolution of existing process models. We also present results
      from applying the algorithm to synthetic data sets as well as process logs
      obtained from an IBM Flowmark installation.},
