Behavior-based Process Comparison in Apromore

This paper presents the integration of three behavior-based comparison operations between logs and/or models into the Apromore process model repository. Each of these operations takes as input a pair of process artifacts (two event logs, two models, or one log and one model) and describes their behavioral differences by means of natural language statements. The generated difference diagnosis has a range of applications of interest to both practitioners and researchers. For example, the difference diagnosis can offer guidance for reconciling discrepancies between business process variants (model2model comparison); can be used to pinpoint and explain differences between actual and expected behavior for conformance checking purposes (model2log comparison); or can explain dissimilarities between normal and deviant executions of a process (log2log comparison).
