Semantic Web services are the next generation of Web services, offering the possibility of an automated Service Oriented Architecture. Much work has been done in the areas of Semantic discover of services based on the semantics of t he operations available through services. There has been further research in this area using the inherent semantics associated with Quality of Service in an effort to discover and choose the appropriate Semantic Web service for a given situation. Because Web services in general expose an organizations infrastructure via this Web interface, there has been a great deal of effort placed in specifying Web service security. Three fundamental standards are the WS-Security, WS-Encryption, and WS-Signature specifications. The work herein focuses on authorization in a Semantic Web services environment. We will look at discovering an appropriate service in which we predict authorization through the use of semantic annotations.
