To solve the bottleneck problem in centralized service discovery methods,a novel architecture based on domain ontology for semantic service discovery is *** distributed architecture can adjust the domain partition and allocate system resources *** characteristics of this mechanism are analyzed,including scalability,self-organization and *** this mechanism,semantic web service discovery is separated into two ***,under balance tree topology,registry proxy can rapidly forward requests to the objective registry center,and avoid the bottleneck ***,a semantic distance based service matching algorithm is proposed to promote the effect of service *** results of simulation experiments show that the proposed mechanism can serve as a scalable solution for semantic web service publication and *** the improved matching algorithm has higher recall and precision than other algorithms.
