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 …

Abstract The Self-Organizing Map (SOM) forms a nonlinear projection from a high-
dimensional data manifold onto a low-dimensional grid. A representative model of some …

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 …

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 …

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 …

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

Powerful methods for interactive exploration and search from collections of free-form textual
documents are needed to manage the ever-increasing flood of digital information. In this …

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 …

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 …

Self-organized formation of topographic maps for abstract data, such as words, is
demonstrated in this work. The semantic relationships in the data are reflected by their …
