Abstract

In this paper we look at a way of combining two or more different classification methods for text categorization. The specific methods we have been experimenting with in our group include the Support Vector Machine, kNN (nearest neighbours), kNN model-based approach (kNNM), and Rocchio methods. Then we describe our method for combining the classifiers. A previous study suggested that the combination of the best and the second best classifiers using evidential operations [1] can achieve better performance than other combinations. We assess some aspects of this from an evidential reasoning perspective and suggest a refinement of the approach.
