基于语义与QoS全局感知的web服务组合
Web services composition based on global semantics and QoS-aware aspect
摘要
Abstract
A global semantics matching and QoS-awarenessservice selection are proposed when aimed at a web services composition process. Both QoS-aware matching and global semantic matching are considered during the global matching. When there are demands for global semantic matching and QoS of service composition, a concrete service set which meets the demands is selected for the whole service composition process and an optimal solution is also achieved. A QoS model is built and the corresponding evaluation method is given for the matching of the service composition process. Based on them, a genetic algorithm is proposed to achieve the maximal global semantic matching degree and fulfill the QoS requirements for the whole service composition process. Experimental results and analysis show that the algorithm is feasible and effective for semantics and QoS-aware service matching.关键词
