This paper describes a data organization system and genuine content-addressable memory
called the WEBSOM. It is a two-layer self-organizing map (SOM) architecture where …

On January 19, 1996 we published in the Internet a demo of how to use Self-Organizing
Maps (SOMs) for the organization of large collections of full-text files. Later we added other …

We present the growing hierarchical self-organizing map. This dynamically growing neural
network model evolves into a hierarchical structure according to the requirements of the …

The current availability of large collections of full-text documents in electronic form
emphasizes the need for intelligent information retrieval techniques. Especially in the rapidly …

Powerful methods are needed for interactive exploration and search from collections of
miscellaneous textual documents that are available in the electronic media. Searching from …

With the WEBSOM method a textual document collection may be organized onto a graphical
map display that provides an overview of the collection and facilitates interactive browsing …

A viable alternative to the traditional text-mining methods is the WEBSOM, a software system
based on the Self-Organizing Map (SOM) principle. Prior to the searching or browsing …

Describes the implementation of a system that is able to organize vast document collections
according to textual similarities. It is based on the self-organizing map (SOM) algorithm. As …

The self-organizing map has already found appreciation for document classification in the
information retrieval community. The map display is a highly effective and intuitive metaphor …

New methods that are user-friendly and efficient are needed for guidanceamong the masses
of textual information available in the Internet and theWorld Wide Web. We have developed …
