ITERATIVE REFINEMENT OF PATHWAYS CORRELATED WITH OUTCOMES

A method for refining a process model includes mining a process model from a set of execution traces; determining whether the process model is too dense or too sparse; learning a predictive model from the execution traces to predict an outcome; modifying the predictive model; and mining a refined process model from updated traces based on attributes present in the modified predictive model. Modifying the predictive model includes making the predictive model more specific if it is determined that the process model is too dense; and making the predictive model more general if it is determined that the process model is too sparse.
