【摘要】 当Web服务技术已成为企业间或企业内部系统间,服务发布和共享的首选方式。Web服务与Agent结合代表了Web服务技术的发展方向之一。服务Agent能够管理一组密切相关的Web服务,并智能化地向外界提供综合的、集成的服务功能。服务Agent内部的规划集合体现了其服务能力。定义了规划的种类、基于目标本体的语义模型和基于ECA规则的语法模型;设计并实现了基于本体推理的目标匹配和基于QoS的规划选择,提出了基于QoS的抽象规划构建;介绍了一个实例和系统实现方法。更多还原

【Abstract】 When the Web Service Technology has become the preferred method to publish and share services among inter-firm or inter-enterprise systems,the combination of Web Services and Agent stands for one of development directions of web technology.Service Agent can manage a group of closely related Web Service and provide comprehensive and integrated services for the environment.The ability of Service Agent is based on a set of plans which are constituted internally.In this paper,the semantic model based on goal ontology and the syntactic model grounded upon ECA rules for plan is defined.And it implements ontology-based reasoning to match goals and develops plan selection based on QoS.Then the paper introduced the construction of conceptual plan.At the end of paper,an example is introduced and Service Agent system is also demonstrated.更多还原
