Abstract
Lacking effective Quality of Service(QoS) support in Web services discovery,a new semantic Web service discovery approach supporting QoS based on fuzzy Particle Swarm Optimization(PSO) was proposed.Firstly,in order to meet users' fuzzy QoS request,fuzzy theory was applied in describing QoS.Then,to improve the PSO,a new theory was proposed that one particle was affected by multi-particles and increment inertia factor was designed.At last,the experimental results have shown the effectiveness of the proposed method.
