Ontology-Based Discovery of Workflow Activity Patterns
Workflow activity patterns represent a set of recurrent behaviors that can be found in a wide range of business processes. In this paper we address the problem of determining the presence of these patterns in process models. This is usually done manually by the analyst, and it requires interpreting the process in terms of the semantics of those patterns. We describe an ontology-based approach to perform this discovery in an automated way. The approach makes use of an ontology, and a mapping between the elements in the given process and the classes in the ontology. A reasoner is then used to discover the patterns, and a SPARQL query is used to retrieve them. The approach is illustrated for a business process in a travel booking scenario.
