Definition of hypertext (1)

 

Hypertext conceives information as nodes and link networks forming navigable paths that can be toured, returned to and referenced.

It is a non-linear way of presenting information as below diagram. Instead of reading or learning about things in the order that predefined by author, editor or publishers, readers of hypertext may follow their own path, create their own order – their own meaning out of the material.

This is accomplished by creating "links" between information (Nodes). These links are provided so that the readers may "jump" to further information about a specific topic being discussed (which may have more links, leading each reader off into a different direction).

Diagram below represent a simple framework how hypertext links different nodes with each other. The blue document is the comment that a reader may attach on the document he/she read(Just like the green footnote added by the author in some of the webpage in this website to comment some quotation from others). The idea is also proposed by Vannear Bush in his Memex Machine.

Hypertext most often refers to text on a computer that will lead the user to other, related information on demand. Hypertext represents a relatively recent innovation to user interfaces, which overcomes some of the limitations of written text. Rather than remaining static like traditional text, hypertext makes possible a dynamic organization of information through links and connections (called hyperlinks). Hypertext can be designed to perform various tasks; for instance when a user "clicks" on it or "hovers" over it, a bubble with a word definition may appear, a web page on a related subject may load, a video clip may run, or an application may open.

Hypertext documents can either be static (prepared and stored in advance) or dynamic (continually changing in response to user input). Static hypertext can be used to cross-reference collections of data in documents, software applications, or books on CDs. A well-constructed system can also incorporate other user-interface conventions, such as menus and command lines. Hypertext can develop very complex and dynamic systems of linking and cross-referencing. The most famous implementation of hypertext is the World Wide Web
