In this article we present a prototypical implementation of a software tool
for document retrieval which groups/arranges (pre-processed) documents bas
ed on a similarity measure. The prototype was developed based on self-organ
ising maps to realise interactive associative search and visual exploration
of document databases. This helps a user to navigate through similar docum
ents. The navigation, especially the search for the first appropriate docum
ent, is supported by conventional keyword search methods. The usability of
the presented approach is shown by a sample search. (C) 2000 Elsevier Scien
