Semantic SLA for Selecting SaaS ERPSeptember 12th, 2022
Service Level Agreement (SLA) is a contract between a service provider and a service consumer. It consists of quality of service (QoS) property and the business properties. In a business environment using Software as a Service (SaaS), SLA and QoS play an essential role in their promising service performance. In this case, the attributes of QoS specified in SLA should show the non-functional attributes of a web service; yet, there, so far, have not been any QoS statement in web service definition language (WSDL) file. This research proposes the selection of SaaS ERP based on the semantic SLA developed using ontology. Analytic Hierarchy Process (AHP) method is employed to establish the rank of a tenant’s SLA,. Subsequently, to create the rank of SLA which has the same AHP scores, the weighted tree algorithm is used. The results show that the combined method (AHP-Ontology) can provide precision reaching at 0.792, better recall at 0.795 and better f-measure at 0.793. Also, the best accurac
