针对服务组合问题,提出了一种既考虑服务输入/输出又考虑服务前提条件/执行效果的结构化组合方法.根据服务请求查找服务组合路径,得到服务依赖图,然后通过依赖图中的依赖关系,把依赖图转化为结构化流程模型,除了标注结构化过程中的某些分支类型时,需要一些额外的用户干预外,整个过程是完全自动的.
This paper introduces a structured service composition method which considers both services' input/output and pre-condition/post-cond ition. It gets service dependency graph by means of searching service compostion path based on service request. It transforms service dependency graph into a structured process model. It is fully automated, besides some additional user input needed to annotate dependencies with specific branching types.
