Although the authors would prefer using defined ontologies that express the domains and specifications of web services, and thus more easily discover and compose these, they know that in the mainstream world represented by the US Department of Defense they will not have those ontologies available soon. In the meantime they have to ensure a transition from structural to semantic methods, including web service discovery methods. In this paper, they are proposing a different approach for dynamic web service discovery that takes advantage of the structure inherent in web services that are defined by WSDL documents. Since the structure is usually based on XML Schema, there is enough information present in these documents to develop a broadly applicable approach.
