The WSMO-QoS Semantic Web Service Discovery Framework
Shuyu Li, Juan Zhou · 2009
Currently, OWL-S and WSMO are two popular frameworks that are used to describe semantic Web service. However, due to mainly focus on the description of the functional part, it is difficult for them to select the best services with consideration of quality of service (QoS). To solve this problem, the WSMO specification is extended and an ontology-based meta-model of QoS called WSMO-QoS is presented in the paper. Furthermore, a QoS-based discovery framework for semantic Web service is proposed, which support service discovery from three phases: basic description, IOPE and QoS. The experiment results validate the effectiveness of the framework.
