In this paper, several problems in associating hyperlinks to text and the diverse possibilities to overcome these problems are discussed. At the current stage, an important aspect is knowledge retrieval of hypertexts. Our advanced studies on hyperlink management focus mainly on a concept similar to Case-Based Reasoning (CBR) systems as a possibility for the automatic generation of links for hypertexts in addition to traditional textual based methods. A detailed discussion of the basic ideas of CBR and an evaluation of its usefulness follows. Finally, methods to evaluate the quality of the proposals are described.
