Abstract in English
Hypertext is a form of electronic document wich includes a number of new features and where the selection of documents is done by association. This technology opens some very exiting new possibilities, particularly for new uses of the computer as a communication and thinking tool. In this work we survey most of the existing hypertext systems, their applications and their design. The advantages and disadvantages of hypertext are discussed and we show in some detail its fundamental features as well as design options for constructing Hypertext Systems, providing a background for several lines of research. Using the ideas developed in this work, we designed and built an Hypertext System called Based Hypertext System for PC--based microcomputer. The user interface employs a form of direct manipulation designed to exploit a two--bottom mouse. The database is a graph of textual nodes that can be distributed across an indefinite number of files and be as large as available disk space permits. The nodes in the database correspond to windows on the screen on a one to one basis. Windows may contain any number of individual items linked to other nodes or used to invoke programs. A browser displays the current node and its neighbors showing how nodes are directly related with each other in the graph.
