Our metrics are defined in terms of
AtomicMetric and ComplexMetric. The metrics and QoS profiles are all defined in
ontology level to reduce the integration cost.
The WSMO provides a conceptual framework and a formal language for semantically
describing all relevant aspects of Web services. There are four main elements:
(1) ontologies, which provide the terminology used by other WSMO elements; (2)
Web service descriptions, which describe the functional and behavioral aspects of
a Web service; (3) goals that represent user desires; and (4) mediators, which aim
at automatically handling interoperability problems between different WSMO elements.
Their nonfunctional properties define a list of general properties definitions,
such as performance, financial, and so on. A semantic matchmaking algorithm is
provided to match service provider??™s and requester??™s goals. Compared with our
profile design, their QoS constraint details are defined in the instance level. How
to reuse these individuals has not been clearly defined in their paper. We define the
QoS profiles in concept level to support high reusability.
