【摘要】 Internet和信息技术的进步为人们提供了丰富信息资源,同时也提出了有效地组织分布式信息资源,为人们提供更为全面、准确、及时的信息服务的要求。 然而要实现这样的信息系统,传统的理论方法和技术难以提供有效的解决途径。本文作者认为融合移动代码技术和软件Agent技术的移动Agent技术因其具有的自治性、移动性、目标/任务驱动性、协作性、适应性,以及移动Agent支持的分布式计算模式所具有的可靠性、智能性、开放性、可伸缩性为实现这样的分布式信息共享系统提供了非常有效的途径。 本文以远程教学信息管理和共享的需要为出发点,将移动代码技术、软件Agent技术有机地结合起来,并探索出了一个基于移动Agent技术的分布式信息管理和共享系统的有效解决方案。在信息搜索和发现的过程中,基于移动Agent的分布式信息共享系统依照用户的愿望在各信息域中搜寻信息,区分相关信息和不相关信息,发现新的信息源,为用户发掘新的信息需求,对信息源进行监控,并把新的和变化的信息及时通知用户。在信息组织方面,该系统通过Agent之间的交互与协作,实现信息的获取、交换和传播。移动Agent技术及移动Agent计算模式为高效的远程教学信息的管理和共享提供了新的、更有效的解决方案。远程教学信息系统建立在一个基于移动Agent技术构建的分布式信息共享系统平台的基础之上,并通过移动Agent技术在远程教学课程信息组织和远程教学课程信息获取两个主要方面的具体应用,对移动Agent的技术优势进行了创新性的发挥。

【Abstract】 With the development of Internet and rapidly growing information in public networks, a distributed information system is required to established to organize information in distributed environment and provides users with a integrated, accurate and in-time information service.However, this kind of information system is not easy to establish. Traditional theories and schemes are hard to produce satisfying result. The author of this paper has the opinion that Mobile Agent technology, which combines Software Agent and Mobile Code technology, is the right means to achieve the goal of efficient distributed information management and sharing, due to its autonomousness, adaptiveness, mobility, coolaborativeness, goal-oriented feature.This paper is called forth by the need of organization and sharing of the education information in remote learning systems, drived by the combination of mobile code technology and software agent technology, and aims to explore a novel way to deal with the management and sharing of distributed information. In information retrieval, the system based on mobile agents aims to satisfy the users’ desire for information; gather related information; discover information resources; dig users’ further information requirements. Information management and sharing in this system are achieved by coolaboration of various agents in this system. Also, this paper discusses the design and implementation of a distance learning information system based on mobile agent technology. In this system, advantages of mobile agent technology are explored and exploited in both of the following two aspects: distributed information organization and distributed information retrieval.
