I agree, semantic Web services (SWS) and this IG have nothing to boast, as I indicated in http://lists.w3.org/Archives/Public/public-sws-ig/2006Sep/0018.html By examining W3C documentation "Web Services Architecture" again @ http://www.w3.org/TR/ws-arch/ we can see why SWS failed and had little accomplishment and progress in the past years. How to realize and implement (semantic) Web services? W3C said clearly: "the requester and provider entities must agree on the semantics and the service description that will govern the interaction between the requester and provider agents, but it would be more accurate to say that they simply need to have a congruent or non-conflicting view of the semantics and service description of the interaction." (Semantic) Web Services Architecture has to be based on "agreement" - if anyone in this SWS-IG would like to read this document again, just count the number of the repeated word "agree" used in this W3C document. However, the leading roles of this IG believed that NOBODY wants to agree with each other, as every developer or service provider has the absolute right to do what s/he wants to do. For this reason, they have to use varied kind of logical modeling to guess which one might be similar to the others, by referencing each individual annotated semantic definition to a super-ontology. Unfortunately, ontology, again by definition, is a shared, common conceptualization of a domain knowledge (or again a kind of agreement/standard). Then we see, those who CANNOT reach an "agreement" have to "share" a super-ontology. This means, after turning around and around through modeling, we return to the starting point - we have to "agree" something first. But the problem is, referencing to a super-ontology promotes the dissemination of individual "semantic" definition on varied service and interface, and this means such people just do NOT use that "shared" ontology of a domain of the service. Why people do NOT use that "shared" super-ontology of a domain of the service, in case there is such a super-ontology? Because they thought standard/agreement-based SWS "takes all the fun out of it", although they knew "That's certainly true" - "given enough clear information about web services", we can write any desired program for interacting with web services, because we reach an agreement first, then those artificially designed "agents" know what and how to do with little fun.

The semantic web is a tool, not a product or market. SInce the semantic web is in its infancy, commercial applications that do use semantic web technology most likely use a significantly scoped down subset of it. The semantic web is more likely to slowly infiltrate various information products and web services rather than suddenly get commercial adoption. Might be tough to find or even classify the cases for your study. Good luck.
