摘要
Web服务组合是为Web用户提供高质量、个性化服务的主要手段,而Web服务选择是进行组合的前提和基础。阐述了蚁群算法的原理,分析了Web服务选择的模型,把蚁群算法引入Web服务选择领域,将基于QoS的Web服务选择问题转化为最优路径选择问题。给出了使用蚁群算法解决Web服务选择问题的实施步骤,对比分析了蚁群算法在不同参数下对服务选择正确率的影响,通过具体的场景测试了蚁群算法对于解决Web服务选择问题的有效性。
The Web Service composition is one of the most important ways to satisfy the users＇ personalized requirements and supply the high quality service for users. And the foundation of service composition is the selection of Web service. The prin- ciple of ant colony algorithm is expounded. The model of Web service selection is analyzed. The algorithm is brought into the field of Web service selection to translate the question of QoS-based Web service selection into the question of finding the optimi- zation path. The steps for solving the question of Web servic,~ selection by the ant colony algorithm are offered in this paper. The influence of the ant colony algorithm with the different parameters on correctness of service selection is analyzed. The validity of ant colony algorithm in solving the problems of Web Service selection was tested in a certain scene.
