Global Map
A global map provides a picture of the entire network of links and nodes. To be useful, this must be depicted graphically, and allow the reader to move and size the view. In most systems, readers may select a new node to make it current. Global maps are of limited utility. Experiments with InterMedia have found that: [A]s the number of connections and quantity of information
increases, so does the difficulty of generating maps of the entire information
web. Since most readers cannot readily understand a diagram with hundreds
of crisscrossing interconnections, the problem of distilling or summarizing
the information must be addressed. (Yankelovich, Meyrowitz, and van
Dam 17) |
