Predicting and Learning Executability of Composite Web Services [chapter]

Masahiro Tanaka, Toru Ishida
2008 Lecture Notes in Computer Science  
Configuring a composite Web service by setting endpoints reduces the cost of development, but raises the probability of a request message triggering runtime execution failures.  ...  To resolve these issues, we model atomic/composite services in a formal specification. Moreover, we apply constraint acquisition algorithm to acquire input specifications of atomic Web services.  ...  We counted failure of the execution of the composite Web service due to failure of any of the atomic Web services as one of the wasteful executions of the composite Web service.  ...
