基于Web服务的Agent模型研究

Research on Agent Model Based on Web Service

提出了一个基于Web服务的Agent模型,来增强web服务的智能性。首先该模型使用服务Agent管理某一领域功能类似的一组Web服务,它使用服务模板来抽象一组功能类似的服务集的特征,并使用规划来表示使用服务模板来完成某一业务目标的过程,这种抽象屏蔽了分布的具体Web服务的异构性,从而使得用户只需要关注于他们所需要完成的目标,而不需要关注如何完成他们的目标。在此基础上提出了一个以规划和服务为中心的BSP(belief,services,plan)Agent概念模型。面向服务的Agent模型弥补了现有Web服务技术的不足,为快速有效的Web服务集成奠定了基础,同时BSP模型也为面向服务的Agent系统的开发提供了理论指导。

This paper proposed a agent model based on web service to improve the intelligence of the web service. By using this model, each service agent man-ages a group of web service with similar functions. The service agent abstracts the features of a group of operations with similar functions as operation template and applies the plan to denote the process of achieving the business goal by using service templates, which shields the heterogeneity of distributed Web services. Therefore the general user only needs to focus on the business goal that they want to achieve rather than how to achieve. Based on the service oriented agent model, the concept model of BSP （Belief, Service, Plan）agent is proposed, which cen- ters on the plan and service. The service oriented agent model overcomes the shortages of present Web service technology, which provides the foundation for efficient Web service integration. Meanwhile, the concept model of BSP agent guides the development of service oriented agent system.
