摘要：Web service composition is a hot and active research area in service oriented architecture (SOA). With highly developing of Web service, users pay more and more attention to quality of service (QoS). In order to obtain high comprehensive quality composite services, an optimizing method was presented in this paper. Firstly, build representative QoS properties quantitative models and QoS aggregation models, then proposed the mathematical model of Web service composition optimizing problem. Secondly, presented an improved artificial bee colony algorithm (I-ABC) and applied to solving Web service composition optimizing problem, I-ABC performance was enhanced by importing taboo strategy and chaos. Finally, some simulation experiments are given, and the results proved I-ABC has perfect performance in Web service composition optimizing than ABC
