Semi-automatic Semantic Service Annotation for SOAP and REST Web Services

Until now, most service annotation has been added the semantics to WSDL, that is a description of SOAP based web services. But REST services have been widely used because of simplicity and usability. In order to discover the most suitable services among various web services and compose them, the integrated service annotation of SOAP and REST web services is necessary. In this paper, we present semantic service framework which is designed for user’s goal based service discovery and composition. And we present the semi-automatic service annotation for SOAP and REST web services. The proposed annotation approach deals with functional semantics, non-functional semantics, and data semantics from web service description and web service portal. Based on this service annotation, it is useful to discover and compose services that satisfy the user’s goal.
