Abstract: A computer-implemented method for analyzing business processes described in a business process execution language includes mapping a workflow abstract model graph from each of a plurality of business process descriptions corresponding to the business processes, identifying message exchange patterns between the business processes, and merging the workflow abstract model graphs into a common graph without connections between nodes associated with the plurality of business processes descriptions. The computer-implemented method further includes adding arcs between nodes of the different business processes descriptions within the common graph according to a merging rule and the message exchange patterns, and mining the common graph for a frequency of path execution, wherein a path is a set of nodes connected by the arcs.
