| Riassunto: | Web Services are emerging technologies that enable application-to-application
communication and reuse of autonomous services over the Web. Recent ef-
forts, OWL-S, model the semantics of Web Services that includes the capabil-
ities of the service, the service interaction protocol, and the actual messages
for service exchanges. However, with the recent proliferation of Web Services
across the web there is a need to automate discovery, selection and execution
of OWL-S services. Also often, no single service can satisfy a user request and
in such conditions, composition of different services in needed to fulfil a user
request. This is the problem of automated service composition, composition
of different available services to fulfil a user request. This report, reviews
current methods of automated service composition and proposes a semantic
implementation of automated service composition, to achieve integration for
Data-as-a-Service (DaaS) web services.
