Les hypertextes : au delà des liens, la connaissance

Abstract : From the reader's side, an hypertext helps him escape the sequential reading of documents, taking advantage of links to browse from one information to another. Thus links are often considered simply as references between documents.

In this article, we propose a deeper analysis of the mechanisms which take place in hypertexts. A link is a semantic relationship between information chunks. As a consequence, two entities are to be considered. On the one hand, information is presented to the reader as node contents. On the other hand, knowledge (with the A.I. meaning) is used by the machine to make browsing possible. Semantic relationships between information chunks represent the knowledge, which is used by the computer to make information closer .

This view of hypertext helps understanding what an author does when he or she designs an hypertext. The web of links that an author creates over information adds value to it and reflects the author's own knowledge. This model also shows very simply the bases of systems such as Intermedia which clearly dissociate the document base from the hypermedia network. This allows several people to express distinct knowledge about a given information base. An hypertext is an organized view of an information set.
