Contextual Aware Dynamic Healthcare Service Composition Based on Semantic Web Ontology

Web service composition is a novel methodology to integrate diverse business solutions to accomplish complex business logic. In this fast-paced digital era with diverse categories of users, intelligent service composition based on the contextual information is highly essential to satisfy individual users requirements. For intelligent composition, ontology based declarative knowledge model is used to describe the business rules, commercial directions and personalized user environment in machine comprehensible way. This paper depicts healthcare service composition with domain ontology to encompass ontology manipulation, contextual information gathering, selecting services and dynamic composition. E-healthcare system automates service composition which invokes hospital, ambulance, scan-laboratory and pharmacy services. It provide valuable information like nearest hospital, best ambulance, scan-laboratory facilities, appropriate department and doctor details by gathering the contextual information of users like location, severity, symptoms, etc. Thus, elaborate search process is eliminated which ultimately helps the user to save time and life in case of emergency situations. thod.
