Contrary to most examples presented later in this book, the primary goal of WWW was never to extend hypermedia research but to apply existing technologies and standards to get a working, world wide hypertext web.

To limit cognitive overload, it can be helpful to provide only a subset of different link types. We propose a link classification that closely fits the first four concepts for navigation in cyberspace (Figure I.22):

Similarityne of the main problems of this approach is that a measure of similarity needs to be defined. Similarity is also called proximity, alikeness, affinity, or association in the literature [Jai88]. Described mathematically, a similarity between two objects i and j, denoted sim(i,j), must satisfy the following three properties:

It embodies most of the popular concepts found in Web browsers on a stand-alone platform but also offers some features not com­monly found in hypertext systems.

Theoretically, there is no constraint on the type and structure of the information items to be stored and retrieved with the information retrieval (IR) system. In practice however, large-scale IR systems are mostly processing textual information.

Naive users, users with a specific background in the search domain, newcomers, and experienced users are all treated the same. The goals that should
