基于代理机制的Internet信息自动提取

An Internet Information Extracting System Based on Agent Mechanism

文章提出并实现了一个基于代理机制的Ｉｎｔｅｒｎｅｔ信息自动提取原型系统，旨在帮助个人及企业用户快速准确地提取满足需要的Ｉｎｔｅｒｎｅｔ信息。该原型系统采用“联邦制”的体系结构，以代理作为架构系统的基本组件，利用代理的自治性和代理之间的协作来完成Ｉｎｔｅｒｎｅｔ信息提取和整理工作。在系统设计与实现中，提出了动态代理的思想，并首次采用站点结构自动转换技术，提高了系统的性能和易用性。基于该原型系统的产品和应用实践证明了该系统的可行性和有效性。

A prototype system based on agent mechanism is presented and implemented to improve the speed and accuracy in extracting Internet information in this paper. The prototype system employs agents as the basic components and organizes them in a federal framework. The task can be done with the autonomy and corporation of the agents. The technology employing in the system including dynamic agent and automatic transformation of Web site structure promote the performance and easy using of the system. The products and applications based on the prototype system are used in practice and prove the feasibility and validity of the system.
