基于领域本体的Web服务动态组合模型

Dynamic Web service composition model based on domain ontology

给出了领域本体、Web服务及服务组合的形式化描述,综合基于业务流程的动态服务组合和基于服务接口匹配的服务组合方法,提出了一种基于领域本体的Web服务动态组合模型。该模型首先把服务请求分解为业务流程,再对业务流程的每个服务按接口匹配方法分解为组合服务。以客户订购产品为例,说明了领域本体的建立方法和Web服务动态组合模型的应用方法。

A formal description of domain ontology and dynamic Web service composition was presented. Based on the composition of dynamic service process and service interface match method, a new domain ontology-based model was proposed. The model decomposed the service request into service processes first, then, based on the service interface match, it further decomposed every broken down service process into composition services. An example of customer subscription was also illustrated to show how to create and apply this new model in enterprise applications.
