Refining Business Process Ontology Model with Invisible Prime Tasks using SWRL rules

A process model is a model that is formed based on user design or event logs. The process model is used as a guidance for process performance analysis. In fact, there are several problems that occur in the modeling processes from the event log. One of them is detecting invisible prime tasks. An invisible prime task is a task that does not exist in the event log, but it is required in the process model to describe the actual processes. Many research suggested methods for detecting invisible prime tasks. However, none of them applied their method in the ontology. This research proposes a method of indicating skip and redo invisible prime tasks in ontology automatically. The method is written in SWRL rule. The experiment shows that the method can detect invisible prime tasks based on the event logs in BPMN ontology as the process model. This method also becomes the pioneer of invisible task detection in the ontology.
