Abstract

In this paper we investigate the use of Self-Organising Maps (SOM) for document clustering. Previous methods using the SOM to cluster documents have used two-dimensional maps. This paper presents a hierarchical and growing method using a series of one-dimensional maps instead. Using this type of SOM is an efficient method for clustering documents and browsing them in a dynamically generated tree of topics. These topics are automatically discovered for each cluster, based on the set of document in a particular cluster. We demonstrate the efficiency of the method using different sets of real world web documents.
