- Abstract
- This paper investigates a novel approach for partifional clustering of a large collection of text documents by using an improved version of the classical Differential Algorithm (DE). Fast and accurate clustering of documents plays an important role in the field of text mining and automatic information retrieval systems. The k-means has served as the most widely used partitional clustering algorithm for text documents. However, in most cases it provides only locally optimal solutions. In this work, the clustering problem has been formulated as an optimization task and is solved using a modified DE algorithm. To reduce the computational time, a hybrid k-means with DE method has also been proposed. The new algorithms were tested on a number of document datasete. Comparison with k-means, a state of the art PSO and one recently proposed real coded GA based text clustering methods reflects the superiority of the proposed techniques in terms of speed and quality of clustering. © 2006 IEEE.
