一种支持Web服务合成的行为建模方法

Approach for Behavior Modeling Supporting Web Services Composition

Web服务之间所蕴含的语义依赖关系,是面向自动Web服务合成的行为建模的关键。基于服务调用的历史信息,通过不动点函数演绎推理出Web服务之间依赖关系的方法,并给出了基于图模型构建服务合成的行为模型的方法以及服务合成向导的方法。实验表明,在一定的数据量内,建立服务合成行为模型的性能呈线性变化,给出的方法是可行和有效的,可以作为自动Web服务合成的支撑技术。

The dependent relationship among Web Services is the key of behavior modeling supporting automatic Web service-oriented composition. Based on the historic data of the service allocation, an approach finding the dependent relationship among Web Services was deducted and reasoned through fixed points, the method of building up the behavior modeling of Service composition based on the map model was given, also the calculating way of producing the guides of service composition was proposed. The experiments showed that, in a certain amount of data, the above behavior modeling appeares linear changes, so the approach proposed is feasible and effective, which could be as technical support of automatic Web service-oriented composition.
