4. A framework for Intelligent Agents and Semantic Web Services integration

Despite their ability to provide a high degree of interoperability across platforms and operating systems, Semantic Web Services infrastructures possess neither enough degree of autonomy nor ability to automatically adapt to changing situations. In these settings, agents can contribute to make systems more autonomous and dynamic, thus maximising their perceived utility. In line with this, the framework presented here comprises both Intelligent Agents and Semantic Web Services working cooperatively in the same environment. Ontologies act as the facilitating technology thus making it possible to exploit the advantages these technologies offer separately. This solution stems from a basic underlying hypothesis: Intelligent Agents and (Semantic) Web Services were conceived for quite different purposes, and so, they must lie on different abstraction layers. The main idea behind Agent Technology was not for Intelligent Agents to be able to provide services, but to act as autonomous entities that incorporate intelligence and cognitive capacities, which allow them to show a goal-oriented pro-active behaviour and to establish, either competitive or cooperative, interaction processes with other software entities in order to satisfy their design objectives. On the other hand, Web Services involved a further evolution in the Distributed Computing field and their only purpose is to provide worldwide-accessible functionality. These conceptual differences between Agent Technology and (Semantic) Web Services Technologies lead to the need to have both technologies working in an integrated environment and glimpse the advantages of their combination in the development of complex systems.
