Semantic Web service discovery framework based on WSMO-QoS

Currently, OWL-S and Web Service Modeling Ontology (WSMO) are two popular frameworks that are used to describe semantic Web service. However, since they mainly focus on the description of the functional part, it is difficult for them to select the best service with little consideration of Quality of Service (QoS). To solve this problem, the WSMO specification was extended and an ontology-based meta-model of QoS called WSMO-QoS was presented. Furthermore, a QoS-based discovery framework for semantic Web service was proposed, which supported service discovery from three levels: basic description, Input-Output-Precondition-Effects (IOPE) and QoS. The experimental results validate the effectiveness of the framework.
