Trust-QoS Based Semantic Web Service Discovery Technology

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. In the end, simulation results demonstrated the effectiveness of the proposed method.
