基于XML的多Agent系统的研究与实现

Research and Implementation of XML-based Multi-agent System

作为构建开放和分布式应用系统的一种主流模式,多 Agent 系统有着广阔的研究前景和应用价值。在统一建模语言(UML)的支持下,面向 Agent 的软件工程研究开始走向成熟。一些面向 Agent 的方法学提供了开发多 A—gent 系统的工具、应用方法或技术。随着 Web 服务技术的发展.XML 成为 Internet 上数据组织和交换的标准。现有研究工作所提出的多 Agent 系统对 XML 文档提供很少的支持。针对上述问题,设计了一个基于 XML 的多 Agent 系统一XMAS。该系统采用带根连通有向图来表示 XML 文档数据模型,并给出相应的文档模式提取算法,XML 文档数据的解析以及时 Web 服务的相关支持。在数据存储过程中的索引优化使得 XMAS 在数据查询上具有良好的性能。

As a widely used pattern for building open and distributed applications, multi-agent systems are becoming a promising paradigm for research and application. Agent Oriented Software Engineering becomes more and more mature under the support of the Unified Modeling Language （UML）. As a result, several agent oriented methodologies for developing multi agent systems have been proposed, with the aim to provide tools, practical methods, and techniques. With the development of Web Service,XMI. becomes a standard for data organization and exchange. The current works have a little support to XML documents in their multi-agent systems. In this paper, we design a multi agent systemXMAS based on XML. We use a Rooted Connected Directed Graph to present XML document data model and give XML schema extraction algorithm. We also offer function of parsing XML document and support to Web Service. During the data store process,index optimization makes XMAS have good performance on data retrieval.
