Objective and SUbjective QoS factors supported Web Service search method based on extended WSDL

With the rapid development of Web Services applications and the increasing popularity, there are numerous functionally similar Web Services available, which made the selection of the Web Services based on functional properties is insufficient. QoS is becoming an important criterion in selection for the best Web Services. In this paper, an objective and subjective QoS factors supported Web Service search method was proposed. The Objective-QoS factors were added by extending the WSDL documents, which should be offered by the service provider. The Subjective-QoS factors comes from users' perspective, represent the actual experiments of the service users. A prototype system was developed to implement both of Objective-QoS and Subjective-QoS factors.
