Abstract |
Despite increasing software support for Business Process Modeling, there are still
misunderstandings, mainly because of terminology mismatches in business process
models. Enriching business process models with semantic annotations derived from
concepts of
a domain ontology aims at overcoming this weakness of Business Process
Modeling.
In this work, we present an approach for adding semantic annotations to business process
elements, especially in activities (tasks and sub-processes) of business processes,
as they
are the main elements of a business process model, using an ontology-based data
matching strategy. Semantic annotations are automatically suggested to the business
designer, based on a composed measure of similarity between ontology concepts and the
activity label of the process to be annotated. The combined similarity measure is an
aggregation of the degrees returned from three similarity measures, aka string, linguistic
and syntactic. Each one of the aforementioned is a priori assigned a specifically weight by
the system. Finally, filtering techniques are used to display options with high relevance
only.
By adding semantic information to process elements the precision of business process
models increases, making them more intelligible to people and machine-readable,
enabling automated reasoning services, such as querying the process space. For this
purpose, we propose an automated approach for querying a business process model
repository for semantically relevant elements and models. A basic BPMN
ontology in OWL
format has been developed for the needs of querying.
Our approach has been implemented in SeMFIS tool, which has been extended to
represent the new functionalities of automated semantic annotations of business process
models. The BPMN language has been used for the representation of business process
models, the OWL format for ontologies and the SPARQL for queries
