Abstract: Semantic Web Services (SWS) focus on developing a machine understandable approach where different sub-services or we can say that small services are combined to form a complex web application. It uses various component services to satisfy a client’s request which cannot be satisfied by any single available services. Here we try to full fill clients request by using Agents capability and for this we try to develop an agent based SWS composition method with two sets of agents i.e. one for Service Requester and other for Service Provider. The agents in SWS are used as clients, service provider and middle agents. The multi-agent based approach presented is further applied on Medical Health planning domain as an application of semantic web technology. The difficulty to achieve the patients’ requirements is a result of availability of large number of consulted doctor on the web and is increasing continuously. This paper presents a model for Semantic web services composition mainly focuses in Medical health planning domain. In this model agents are able to understand the requirement of the patient and interact with him like a human expert. It focuses on how patients request is proceed to provide information at patient location as a composition of different aggregated web services.
