A Reliability Evaluation Framework on Composite Web Service

The composition of web-based services is a process that usually requires advanced programming skills and vast knowledge about specific technologies. How to carry out web service composition according to functional sufficiency and performance is widely studied. Non-functional characteristics like reliability and security play an important role in the selection of web services composition process. This paper provides a web service reliability model for atomic web service without structural information and the composite web service consist of atomic web service and its redundant services. It outlines a framework based on client feedback to gather trustworthiness attributes to service registry for reliability evaluation.
