摘　　要：Web服务是设计和构建企业业务应用的重要技术,单个的Web服务由于功能有限很难完成一个复杂的业务流程,因此需要对现有的独立Web服务进行组合.采用服务链组合方法实现服务组合,在服务链的构造过程中引入数据挖掘中的关联规则方法,将原子Web服务的定义简化为输入参数和输出参数,在此基础上运用关联规则对原子服务相互之间的内在关系即关联关系进行分析,然后选择强关联的服务来做参数匹配.最后根据服务请求来选取其中的一条服务链作为实现业务需求的最佳执行策略.通过实验给出了由规则构造服务链的具体实施步骤.Web services are becoming an important technology for design and construction enterprise business application. Generally, it＇s necessary to combine web services because a single web service is difficult to complete a complex business process. Service chain is used to realize service composition. Association rules of data mining are introduced in the construction process of the service chain. Simplify the definition of web services is as an input and output parameters. Then the intrinsic relationship among atomic services is analyzed by association rules, the services with a strong association are chosen to do parameter match. Finally, according to the service request to select a service chain as one of the best execution strategy meets business needs. The experiment demonstrates the concrete implementation steps for structuring the chain of web services by association rules.
