Issues on hypertext design
The links between the nodes constitute one of the most significant aspects of the hypertext, and very much contribute to the support of their dynamic interaction paradigm, so relevant to the implementation of effective applications.
In this paper we point out some of the main problems the hypertext applications' designer must face. Afterwards, we outline a hypertext design methodology that leads to a consistent design of the nodes' structure, and allows modelling the different kind of links that can exist among the nodes. In particular, introducing the “concept space” allows an effective modelling of the intensional links. A special attention is dedicated to the representation of the navigational aspects, that can be made evident to the user by means of a map of the links, based on the concept of affinity between the nodes. Finally, we discuss some general implementation aspects, and point out the need of offering to the user multiple and interchangeable interaction paradigms.
