A common situation within Web Service usage is that the functionality
provided by a Web service does not precisely match with the one
requested by a client. In order to handle such functional
heterogeneity, general purpose reasoning procedures for central
reasoning tasks like Web service discovery become complex and thus
expensive with respect to time and resource consumption. With respect
to Web scalability, a technique is presented for increasing the
efficiency of functional discovery for Semantic Web services.
Therefore, so-called Delta-Relations are introduced that denote the
explicit logical relationship between functional descriptions of Web
services and requests. On basis of these, collections of related goals
with semantically described relations are determined automatically,
referred to as goal ontologies. This additionally gained knowledge on
the correlation of goals as the driving elements for using Web
services is utilized for omitting or reducing the need of expensive
