Abstract
The subject areas of psychology, artificial intelligence, education, information science and now hypertext employ a common representation to structure knowledge and information. The various interpretations applied to this representation and the uses made and phenomena modelled with it in the different subject domains are examined. The application of these different meanings and functions to hypertext are briefly considered and the covergence of hypertext and these other subject areas in intelligent tutoring is discussed. The importance of structure with this notation is considered throughout.
