Toward Ontologies or Web Services Matching

Sorry for the probably noob question. :-)
In the retrieving-informations work for my thesis i'm currently working 
on the state of the art of the capability matching and i still don't get 
a thing: is the Semantic Web directed to the ontologies matching or 
toward webservices matching? I ask this because ant the moment i can 
only found some "theorical" approaches to the semantic matching of web 
services, while ontology matching seems a more advanced field and seem 
to have more experimental results. Is it because of the spreading of the 
ontology based tecnology or just because in fact the matching of the web 
services is too "old style" or based on the services itself? Where could 
i found some sources on it?

Thanks in advance.
