Hypertext Beginners: Beginning users of a body of knowledge have no understanding of the subject, language, or classification schemes peculiar to the knowledge base. A hypertext system can be structured with an abridged, sequential format as a means of effectively introducing a neophyte user to unfamiliar information. This introductory overview can present the scope and limits of the knowledge base, the structural classifications of knowledge in the system (the system taxonomy), and describe the mechanism for the effective operation of the system itself. The command language and syntax of a hypertext system are most effective if they are coherent and easy to assimilate. A new user of a hypertext system should be quickly capable of retrieving useful information from the knowledge base. Road Maps: Navigating a Knowledge Base Iterative Learning
