Ontology-based Dynamic Reliability Evaluation Model for Web Services
Min Xia · 2012
Current reliability evaluation approaches lack a formal semantic representation and the support of incomplete or uncertain information.To fill this gap,Web service reliability ontology(WSRO) was developed.WSRO is mapped to a probability graphical model,and on this basis,the Web service reliability evaluation results can be obtained by the causality reasoning.This approach can solve the problem of the lack of semantic description,assess the reliability of Web service,and lay the foundation for Web service auto-discovery,auto-composition and auto-execution.Experimental results show that the approach is feasible,applicable and effective.
