Service discovery plays a very important role in web service applications.Current web service discovery mechanism mainly depends on the functional web services description.Large growth in number of web services as well as the growth in the number of re-gistries makes this replication impractical.Web services discovery mechanism with unfunctional description is put forward.A model for web service discovery and selection based on QoS constraints is proposed,furthermore,a feedback mechanism is used to support dynamic evaluation of web services.By using a new concept weight,this model realizes the dynamic sorting of web services which meets the personal requirements of consumers,and improves the precision of selection.
