摘要
为满足用户按需交换动态信息的要求,Web服务应当可以动态按需协同工作,完成任务,提供信息,即动态地按需集成Web服务。服务发现是服务组合的关键问题。针对现有的服务发现方法要么依赖关键字查找,查准率低;要么基于语义描述,难以保证服务组合的性能和质量。在场景驱动的业务模型构造方法基础上,构建了一个基于场景的按需服务集成方法框架,提出了一种依据"先筛选后匹配"原则的服务自动发现方法。测试验证该方法具有高查全率和低查错率的特性。
In order to satisfy the acquirements of based - requirements exchanging dynamic information, Web services should cooperate dynamically, accomplish task and provide information, seemed as based - requirements integrating Web services, services discovering is the key of services combining. Based on the method of scenario- driven business model constructing, a frame of scenario- driven services integrating and a method of automatic Services discovering was proposed, which keeps to the principle of ＂first riddling, second mapping＂. The experiment proves that it has higher recall and lower false positives.
