QoSOnt: a QoS ontology for service-centric systems

This paper reports on the development of QoSOnt: an ontology for quality of service (QoS). Particular focus is given to its application in the field of service-centric systems. QoSOnt is being developed to promote consensus on QoS concepts, by providing a model which is generic enough for reuse across multiple domains. As well as the structure of the ontology itself an example application currently in development - SQRM (service QoS requirements matcher) - is discussed. This application is used to highlight some of the advantages of the ontology including standardisation and the level of machine understanding of QoS specifications which can be achieved.
