| 摘 要： | 在SOC中,往往利用已有的服务进行组合,产生用户需求的组合服务.为满足用户的需求,服务组合的模式可能是多种多样的.针对这一问题,用环境本体语言描述需求和服务组合,结合Petri网的相关理论,构造了一种服务组合需求的Petri网模型.通过对服务组合的Petri网模型分析,结合库所吸收规则,将其简化.构造可达树的算法,进而提取功能上等效的服务组合模式.最后,结合旅游安排经典案例验证了算法的可行性.

| Abstract: | In SOC,the composition of multiple web services was applied to satisfy the given request.To meet the request,the compositions of the services were different.Aimed at such difficulty,described with the environment ontology,the relative theory of Petri net was proposed to build up the service composition requirement model.The requirement model was analyzed and simplified according to the absorbing rule of Place.An algorithm of reachable tree was proposed to give the service composition mode on the function.Finally,a classic example of travel arrangement was used to verify the theory. |
