Modelling Business Processes in OWL-S

Li Guo

OWL-S is used to support automated discovery, composition, invocation and monitoring of web services. However, OWL-S is an XML based syntax that is hard to use for those with little XML knowledge, which presents obstacles at requirements capture and design stages. In contrast, diagram based business process modelling languages like FBPML include standard process constructs familiar to this target user group. Such methods are semantically richer than an OWL-S styled modelling language, but do not provide direct inputs for web service development and cannot be used by agent systems straightforwardly. In order to bridge this gap, automatic translation from diagram based business process models to web services models is necessary. I will talk about such translation by applying conceptual mapping techniques, demonstrated by using concrete mapping examples from FBPML notations to OWL-S Process Ontology. Some problems identified during the mapping process will also be mentioned.
