The discovery of suitable Web services for a given user requirement is one of the key technology. A mechanism is proposed to support QoS-based semantic Web service discovery. Firstly to reduce the overhead and enhance the discovery efficiency, genetic algorithm is adopted as a method of service clustering. Furthermore, the evaluation and calculation of QoS was realized to satisfy the user's QoS requirements...
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...
Discovery of suitable Web services for a given user requirement is one of the key technology. A mechanism is proposed to support QoS-based semantic web service discovery in the paper. Firstly, to reduce the overhead and enhance the discovery efficiency, genetic algorithm is adopted as a method of service clustering. Furthermore, based on user's QoS requirements, the QoS-based service matchmaker was...
