服务请求驱动的语义Web服务组合方法

Service Request-Driven Semantic Web Service Composition

以Web服务本体和领域本体为基础,利用语义匹配算法,提出一种以服务请求驱动的服务组合方法。递归调用此算法可以得到满足服务请求功能及性能约束的服务组合树。通过一个具体的实例,讨论服务组合树的构造过程。实例应用表明,本方法支持自动的、动态的Web服务组合,能够很好地满足QOS约束。

Using the semantic matching algorithm, this paper proposes a service request-driven service composition method based on Web services ontology and domain ontology. By recursive calls this method to find the combination tree which should satisfy the service request function and performance constraints. To explain how to get the combination tree, a concrete example is used in this combination method. Example applications which support automatically and dynamic Web service composition can satisfy QOS constraints.
