Abstract:We contribute performance functions to model the quality of service (QoS) of web services in horizontal composites. Performance functions are thereby used to formalize service level agreements (SLAs) to enable automated verification. Inter-Component rating is a model for gathering additional QoS information from web services that rate the output of their predecessor web services in composites. Furthermore, we contribute two approaches to verify if a web service adheres to its claimed QoS described with a perfo… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
