Web服务的合成是Web服务的一项增值服务,如何根据已有的服务动态合成所需要的服务,是一个重要的研究课题。本文以实用性为原则,兼顾效率,提出了一种基于领域本体的Web服务合成模型。该合成模型首先利用本体概念消除了Web服务合成中的语义问题;然后利用后继服务合成方法,进行Web服务的合成;最后利用合成缓冲区来筛选最佳合成策略,以提高合成效率。本文通过实验测试了该合成模型的性能,并给出了总结。
The synthesis of Web Services is a value-added service of Web Services. How to dynamically synthesize the required services according to the existing services is an important research topic. Based on the principle of practicability and taking efficiency into consideration, this paper proposes a Web service composition model based on domain ontology. The synthesis model firstly uses the ontology concept to eliminate the semantic problem in the synthesis of Web services. Then, the synthesis of Web services is carried out by the successor service composition method. Finally, the synthesis buffer is used to screen the best synthesis strategy to improve the synthesis efficiency. In this paper, the performance of this synthetic model is experimentally tested and the conclusion is given.
