Web Service Composition with Petri Net and Ontology
Azizbek Marakhimov, Yim Jaegeol, Jaehun Joo · Frontiers in artificial intelligence and applications · 2013
A web service is a function that can be invoked anytime by any program on the Internet. Making use of web services, we can very efficiently develop a new software system. However, automatic composition of web services is challenging because independently developed web services are not always compatible. Many studies suggest mediation as an effective method of composing heterogeneous web services. Among them, Petri net and ontology-based mediation is eye-catching. This paper introduces a web service composition solution that builds Petri net model of interactions between web services and ontologies representing domain knowledge, then combines the Petri net models with ontology-based mediation.
