Abstract
Technological advancements in the Web services standards have lead to the development and deployment of broad applications in open and dynamic environment. These standards enable the services to be discovered and invoked dynamically. In current web, due to lack of semantics, agents cannot understand services that radically influence the negotiation, coordination and cooperation among the heterogeneous environments. Hence semantics play a vital role to bring automation in the current web and are highly desirable to enhance the capabilities of Web services. We believe that the vision of the semantic web can be realized if the agents are intelligent enough to process and interpret the semantic content based on the understanding which they have developed about the contents through the use of attached ontologies, since the agents have well defined reasoning, decision making, and interaction mechanisms. Our research objective is to propose new paradigm for interactions among semantic web services and software agents for problem solving. In this paper, our focus is to address the issue of negotiation between agents and semantic web services and present our initial work towards the solution, by presenting how the agents can discover, invoke and negotiate with the Semantic Web services for the autonomous service provisioning and consumption. We have achieved this interoperability, where the agents can efficiently communicate with the Web services in the dynamic and heterogeneous environments.
