In my view a Web service includes both the WSDL definition (the "interface syntax") and its semantics. I would only decide to use a Web service after knowing its semantics.

The problem is that so far we only have a standardized way of describing the interface. The current work of the WSD group on RDF/OWL is an attempt to provide a standardized way to describe the semantics. But again the concept of Web service should include both the interface and the semantics behind.
