Behavior Similarity Measure Method for Artifact-oriented Business Process

Artifact-oriented business process is the representative of data-centric business process.Similar with traditional control-centric business process,it is a critical issue to determine the similarity or the distance between two processes which would enable a better operation of the Artifact-oriented business model,such as process retrieval,process mining,etc.A novel behavior similarity measure method for Artifact-oriented business process is proposed.Firstly,this method computes the similarity of business core data in the process by measuring the similarity of key Artifact.Secondly,it measures the task dependence relation in the task executing paths according to the lifecycle characteristic of key Artifact.Finally,it measures the similarity of key Artifact attribute assignment sequence in the task executing path.Theoretical and instantiation analysis also demonstrate the validity of this method.
