提出了一种基于事件本体的Web服务动态组合方法.将服务与事件本体中的事件类进行映射,组合服务即是本体中的复杂事件类,服务请求即是一个事件的实例化.用户输入服务请求以后,可以通过事件本体的推理,找到用户请求对应的事件类;再根据事件本体中的事件间关系进行推理,找到它的组成事件类或者后继事件类,从而得出服务和服务之间的关系和交互;最后根据组合规则执行服务.实例验证该方法是有效的和可行的.
This paper proposes a method of dynamic combination of Web services based on event ontology, which maps event classes in service and event ontology, which is a kind of complex event in ontology, which is an event instantiation.User input service After the request, you can find out the event class corresponding to the user request through inference of the event ontology, and then deduce it according to the relationship among the events in the event ontology to find its constituent event class or successor event class, so as to find out the relationship between the service and the service Relationship and interaction.At last, the service is executed according to the combination rules.Examples verify that this method is effective and feasible.
