Li Bi · Ningxia Engineering Technology · 2012
With the sustained and rapid development of network information,more and more web services have been published on the Internet,there will be a lot of Web Services with the same function and different Quality of Service,how to find Web Services that best meet the needs of service requesters become a hot research in the service fields.So the model of original Web Services system is extended,the model of Quality of Service is established,the extended model of Web Service is analyzed,the extended model of Web Service discovery is analyzed.Quantification method of Web Services based on QoS is researched,according to the real application situation,in the original description of Web Services based on the function,QoS have been increased,and the practical parameter is set up.According to the characteristics of QoS requirements of different requesters,computing the Quality of Service of similar service,Experimental results show that the method can meet the services requester with the service request of QoS,the best service will be found,the method has higher practicability and feasibility.The method has higher accuracy than traditional method.
