An Ontology for Quality-Aware Service Discovery

Authors

Abstract

The fast emergence and acceptance of service oriented architectures leads to fast development of extensional technologies like service delivery, discovery and composition. As main effort is being spent on automatic discovery and composition, current solutions do not reflect real world scenarios sufficiently. Services are offered by different vendors with different quality levels and prices. Large service oriented architectures with dynamic service compositions are not able to adapt without manual inspection of service quality and negotiation of service contracts. We propose an ontology for modelling Quality of Services (QoS) and Service- Level-Agreements (SLA). A semantic approach should bridge the gap of different terminology, languages and metrics making Service-Level offers and requests agent understandable and automatic quality-aware discovery possible.
