网络计算模式对信息处理的研究产生了深远的影响，而Ｊａｖａ技术的平台独立性等特点使得信息获取机制的研究更具有现实意义。文中阐述了在Ｉｎｔｅｒｎｅｔ和ＷＷＷ上进行信息获取机制的研究与实现的框架结构，以及用Ｊａｖａ实现的两个实验系统ＲＥＤＵ／ＴＨ－１和ＩＮＳ／ＴＨ－１，前者用于交互式远程教学，后者用于在Ｉｎｔｅｒｎｅｔ上的智能检索导航。
Network computing model has far-reaching impact on the research of information processing, and the platform independence of Java technology makes the research of information acquisition mechanism more practical. This paper describes the framework of the research and implementation of information retrieval mechanism on the Internet and WWW, and two experimental systems REDU / TH-1 and INS / TH-1 implemented in Java. The former is used for interactive distance learning and the latter Used for intelligent retrieval navigation on the Internet.
