Abstract—Innovative methods that are user friendly and efficient are needed for retrieval of textual information available on the World Wide Web. The self-organizing map (SOM) is one of the most widely used neural network algorithms. SOM can be used to identify clusters of documents with similar context and content. In this paper, we explore and visualize the Self Organizing Map and discuss how to classify text documents. The paper also portrays the capabilities of SOM in text classification. We also discuss about experiments done using 20 news group dataset.
Index Terms—Self-organizing map, stop words, term-document, neurons.
