QoS ontology for service selection and reuse
Résumé
Web service technologies become popular in software development in all sectors. Even service related standards are defined, they still have limitations to represent the services. Some examples of the limitations are : service registry does not support the QoS properties, web service description language (WSDL) does not allow specifying the QoS properties and there is no common description for defining the web service structure. Our research aims to enhance the service description structure to support the service selection and composition process
in order to reduce development costs. The existing resources are analyzed in order to define a Web Service Ontology (WSOnto). Furthermore,
a service selection algorithm is proposed for validating the proposed WSOnto. This service selection algorithm considers multiple criteria as inputs : application context, input, output, weight of the QoS performance and service’s security properties. Furthermore, a QoS calculation method is proposed to obtain a better QoS values.
