Abstract: |
This paper analyzes the reason of BPMN emergence and points out that business processes in BPMN2.0 need semantic information to align Business and IT. In order to supplement semantic information in BPMN2.0, four methods of ontology-based semantic annotations are proposed and they are all built on the extension mechanism of BPMN2.0. The advantages and disadvantages of the four methods are subsequently discussed. This paper also discusses how semantic annotations benefit the vertical model transformation of business processes. |
