Handling Failures in Semantic Web Service Composition Through Replacement Policy in Healthcare Domain

Consistency of web service composition is a challenge for developing business applications. As web services are naturally changeable, the way to deliver consistent web services composition over unreliable web services could pose a significant problem. We propose a framework for semantic web services in healthcare domain that automatically performs web service discovery, composition and quality of service assurance, and, performs error handling through the replacement policy and fault-tolerant composition of web services that mixes both exception managing and transaction approaches. The framework enables the development of personalized healthcare systems.
