TAO - Transitioning Legacy Applications to Ontologies

Abstract

Semantic-based software engineering has attracted a lot of attention recently from the Semantic Web community, and from the Software Engineering community who want to understand how to migrate existing, legacy systems to services that can exploit the use of semantics. However, to facilitate such a transition, a methodology is desirable, that considers the challenges of knowledge acquisition and modeling given the existence of both service descriptions, code, and support documentation. In this seminar, I will introduce the need for a methodology, and highlight some of the challenges in modeling the ontologies for both service annotation and support-document annotation, and then introduce the use of both formal models and procedural models. As the use of a Semantic Web Service Framework is crucial in the transitioning process, we also present two contrasting views of the most significant efforts to date: OWL-S and WSMO.
