A dynamic linkage method for text data based on self-organizing map

Database systems have become larger and it is not so easy for users to get the information which they want. Hypermedia systems have become increasingly popular as tools for information retrieval, however, links in hypermedia are static and have to be defined manually hands. Furthermore there are problems in evaluation methods for these database systems. This paper describes a dynamic linkage method for text data based on the self-organizing map. The feature of our approach lies in the fact that this method automatically groups texts and generates links among them. We also propose an evaluation method for the self-organizing map. A prototype system was developed and some experiments were carried out to evaluate our system
