MFI-5 Based Similarity Measurement of Business Process Models.

With the increasing use of business process model management techniques, a large number of business process models are being developed in the industry, so the corresponding enterprises and organizations usually need to maintain a large business process set. An approach is presented based on the Meta-model for process model registration (MFI-5) to accurately measure the similarity of process models. First, based on MFI-5, the Process Model Description Framework (PMDF) is constructed. According to PMDF, a similarity feature set of the process model (SFS) is defined. Second, the Business Process Modeling Notation (BPMN) is utilized to describe corresponding business process, and the BPMN models are obtained. Further the BPMN models are identified and quantified by using SFS, so the model vectors are obtained. At last, the Tanimoto Coefficient-based algorithm is utilized to calculate the similarity between any two vectors, the similarity measure matrix of the BPMN models can be extracted. We illustrate the approach in the context of measuring the similarity of the online sales service processes, the result of which shows that the proposed approach can facilitate business process recommendation.
