A computer-based text retrieval system that enables the user to provide access to or gain information related to a particular text.
Hypertext, in computer science, a metaphor for presenting information in which text, images, sounds, and actions become linked together in a complex, nonsequential web of associations that permit the user to browse through related topics, regardless of the presented order of the topics. These links are often established both by the author of a hypertext document and by the user, depending on the intent of the hypertext document. For example, traveling among the links to the word iron in an article might lead the user to the periodic table of the elements or a map of the migration of metallurgy in Iron Age Europe. The term hypertext was coined in 1965 by Ted Nelson to describe documents, as presented by a Computer, that express the nonlinear structure of ideas, as opposed to the linear format of books, film, and speech. The term hypermedia, more recently introduced, is nearly synonymous but emphasizes the nontextual components of hypertext, such as animation, recorded sound, and video.
The integration of any combination of text, graphics, sound, and video into a primarily associative system of information storage and retrieval in which users jump from subject to related subject in searching for information. Hypermedia attempts to offer a working and learning environment that parallels human thinking- that is, one in which the user can make associations between topics, rather than move sequentially from one to the next, as in an alphabetic list. For example, a hypermedia presentation on navigation might include links to astronomy, bird migration, geography, satellites, and radar. If the information is primarily in text form, it is regarded as hypertext; if video, music, animation, or other elements are included, the information is regarded as hypermedia.
