【摘要】：针对Petri网理论与方法在服务计算中的应用,从Web服务执行的角度,在定义Web服务组合的Petri网的基础上,给出Web服务组合的Petri网的自动生成方法.首先对Web服务的Petri网描述,通过利用Web服务的输入、输出等元素的本体定义为Petri网中相应库所元素添加语义标签,得到Web服务的Petri网的PNML(Petri net Markup Language)+OWL(OntologyWeb Language)描述,其中PNML部分描述Petri网的网结构,OWL部分描述Petri网中各库所元素的语义标记;进一步,在已得到Web服务组合中各子Web服务之间输入/输出关联元素的基础上,确定各子Web服务的Petri网之间的可融合库所,通过执行可融合库所之间的库所融合操作,将各子Web服务的Petri网合并得到Web服务组合的Petri网,为Petri网相关理论与方法在服务计算中得到实际应用提供了必要的前提.
[Abstract]:Aiming at the application of Petri net theory and method in service computing, from the point of view of Web service execution, based on the definition of Petri net of Web service composition, an automatic generation method of Web service composition Petri net is presented.Firstly, the Petri net description of Web service is described. By using the ontology of the input and output elements of the Web service, the PNML(Petri net Markup language (OWL(OntologyWeb language) description of the Petri net of the Web service is obtained by adding semantic tags to the elements of the corresponding library in the Petri net.The PNML part describes the network structure of the Petri net and the semantic markup of the elements of each library in the Petri net. Furthermore, on the basis of obtaining the input / output correlation elements among the sub-#en4# services in the Web service composition,The fusible library stations between the Petri nets of each sub-#en0# service are determined. By performing the fusion operation of the libraries between the Web services, the Petri nets of each sub-#en2# service are merged to obtain the Petri net of the Web service composition.It provides a prerequisite for the practical application of Petri net theory and method in service computing.
