一、超文本技术的发展和特点 超文本技术早先是应用于图书、文献资料、档案等领域的一种信息管理技术。早在1945年,美国弗兰克林·罗斯福总统的科学顾问Vannevar Bush提出一种叫做Memex(Memory extender存储器扩充)设备的设想。设想中的Memex是一种能存储书籍、档案、信件等文本信息,能提供一种简单的方法在文件之间建立链结,能帮助用户建立索引来组织信息,并能提供快速、灵活查阅的设备。超文本(Hypertext)的术语是60年代Ted Nelson创造起用的,他认为“任何事物之间都有很深的联系”,他构想了块状的超文本,读者在读完一块超文本之后,可自由的决定下次要读的那块超文本。1990年两位物理学研究人员提出为建立一个适用于包括技术文档,报告,数据库等不同类型数据的统一用户界面,产生了一种在
First, the development and characteristics of hypertext technology Hypertext technology was previously used in books, documents, archives and other areas of an information management technology. As early as 1945, Vannevar Bush, a scientific adviser to President Franklin D. Roosevelt of the United States, proposed a concept called Memex (Memory extender memory expansion) device. The envisioned Memex, which stores textual information such as books, files and letters, provides an easy way to create links between documents, helping users to index information to organize and provide quick and flexible access equipment. The term Hypertext was created by Ted Nelson in the 1960s. He thought “there is a deep connection between anything.” He conceived block-style hypertext, and readers were free to read a piece of hypertext The piece of hypertext to decide next time. In 1990, two physicists proposed that to create a unified user interface suitable for different types of data including technical documents, reports, databases, etc.,
