Examples of customizable components are given in the third section. Implementation of prototype systems is described in the fourth section. The fifth section discusses problems of evaluation. The final section discusses possible future work. It is possible to display a CIC in different presentation formats, and this is commonly done.
Most Web browsers allow users a least a limited menu of such presentation options.
For example, users can choose colors for background or hyperlinks. However, it is also possible to modify the information content of the CIC to better meet the needs or preferences of a particular user. For example, an abstract could be presented instead of the entire document. Or the document could be translated into a different language. A graph could be redrawn in a different format.
